The sensors are operational without any additional components. The electrical connection is established via DIP solder pins and pressure is connected either by u s- ing flexible tubing on the metal tubes or a suitable flange. The sensors in the AMS 5915 series are available in various pressure ranges for all pressure types: differential (relative) pressure sensors in ranges sure types from 0 ... 500 mbar up to 0 … 2 bar and 700 ... 1200 mbar for barometric measurements. Bidirectional differential sensors are available in -1 ... +1 bar. Custom specific p ressure ranges or modifications are available on request.

The temperature output value is the overall sensor temperature . It is measured at the sensor’s signal conditioning ASIC and is influenced by the measurement media’s temperature, the ambient temperature, the sensor’s self -heating and the thermal conductivity of the material in contact to the sensor (e.g. PCB, mounting assembly, pressure hoses). 5) Total accuracy is defined as the maximum deviation of the measurement value from the ideal characteristic curve at room temperature (RT) in %FSO including the adjustment error (offset and span), nonlinearity, pressure hysteresis and repeatability. Nonlinearity is the measured deviation from the best fit straight line (BFSL) across the entire pressure range. Pressure hysteresis is the maximum deviation of the output value at any pressure within the specified range when the pressure is cycled to and from the minimum or maximum rated pressure. Repeatability is the maximum deviation of the output value at any pressure within the specified range after 10 pressure cycles. 6) The TEB (total error band or overall error) is defined as the max imum deviation of the measurement value from the ideal characteristic curve in %FSO across the entire temperature range (-25 ... 85 °C). 7) Media compatibility of pressure port 1 (for a description of port 1 see Figure 5 and Figure 6): clean, dry gases, non-corrosive to silicon, RTV silicone rubber, epoxy, gold (alkaline or acidic liquids can destroy the sensor). For standard packages with tubes the media compatibility of the nickel-plated steel tubes has to be considered, too. 8) Media compatibility of pressure port 2 (for a description of port 2 see Figure 5 and Figure 6): fluids and gases non-corrosive to silicon, Pyrex, RTV silicone rubber. For standard packages with tubes the media compatibility of the nickel-plated steel tubes and its epoxy adhesive has to be considered, too.
Board Mount Pressure Sensor AMS 5915 SERIES © 2023, Analog Microelectronics GmbH www.analog-micro.com Datasheet AMS 5915 – Rev. 4.1 6/15 FUNCTIONAL DESCRIPTION The pressure sensors in the AMS 5915 series combine a high quality , membrane-based piezoresistive sili- con sensing element with a modern mixed-signal CMOS ASIC for signal-conditioning on a ceramic substrate. This enables a low total error band, an excellent temperature behavior and long -term stability. AMS 5915’s functional principle is explained using Figure 1. The physical pressure applied to AMS 5915’s pressure port(s) is converted into a differential voltage signal at AMS 5915’s piezoresistive pressure sensing element. This differential voltage is signal -conditioned and converted into a standardized digital voltage output signal in the following way: At first the sensing element’s differential voltage signal is pre -amplified, transmitted to the A/D converter block (ADC) by the multiplexer block and converted into a digital signal with 14 -bit resolution. This di gitized signal is processed mathematically by the ASIC’s integrated microcontroller unit (μC) to achieve a calibrated and temperature compensated output signal. For this purpose the μC uses a correction algorithm and individual correction coefficients stor ed in the ASIC’s EEPROM during AMS 5915’s factory calibration process. This permits sensor -specific calibration and correction (i.e. linearization and temperature compensation) of the digitized pressure signal. The temperature signal necessary for temperat ure compensation is generated at the ASIC’s temperature reference block and is transmitted by the multiplexer to the ADC, where it is digitized, too. The ASIC’s microcontroller runs a cyclic program, which continuously calculates the current standardized and corrected digital pressure value using the present digitized pressure and temperature measurement values and the stored correction coefficients. In addition, a standardized digital value of the current temperature is calculated. These calculated and cor rected digital values (14 -bit pressure value and 11 -bit temperature value) are written to the ASIC’s output registers and are continuously updated (typically every 0.5 ms). The readout of the standardized digital output values for pressure and temperature from the output registers is done via the sensor’s I²C interface at PIN3 (SDA) and PIN4 (SCL). The AMS 5915’s digital output values (for pressure and temperature) are not ratiometric to the supply voltage. Figure 1: Functional principle
Board Mount Pressure Sensor AMS 5915 SERIES © 2023, Analog Microelectronics GmbH www.analog-micro.com Datasheet AMS 5915 – Rev. 4.1 8/15 I2C-INTERFACE AMS 5915 pressure sensors have a digital output (I²C-interface). When connected to a bidirectional I²C-bus, the current corrected digital pressure and temperature values can be read from AMS 5915’s output register via the I²C-interface. Communication via the I²C-bus follows a simple master-slave principle. Data transfer is always initialized by a master (such as a microcontroller), which sends a data request to the sensor; the AMS 5915 sensor – which always operates as slave – answers then. The I²C-bus requires just two bus lines: a serial data line (SDA) and a serial clock line (SDL). SDA and SCL are bidirectional lines, which are connected to the positive supply voltage using pull -up resistors. AMS 5915 communication protocol adheres to a standard I²C communication protocol (given in Figure 3)1. 1 There are three differences of AMS 5915’s communication protocol compared to the original I²C communication protocol: 1. A stop condition directly after a start condition without clock pulses in between is not allowed. This creates a communication error for the next communication. 2. A second start condition (restart) during data transmission when SCL is still high is not allowed. 3. Between the start condition and the first rising SCL edge a falling SDA edge is not allowed. Figure 3: Standard I²C protocol
Board Mount Pressure Sensor AMS 5915 SERIES © 2023, Analog Microelectronics GmbH www.analog-micro.com Datasheet AMS 5915 – Rev. 4.1 9/15 The I²C communication phases are as follows: Idle period (bus is free) When the bus is free, both I²C-bus lines (SDA and SCL) are pulled up to supply voltage level (“high level”). Start S (start condition) Prior to any data transfer on the bus a start condition has to be generated. The start condition is always sent by the I²C-master. The start condition is defined as a transition from “high level” to “low level” on the SDA line while the SCL line is still on “high level”. The digital data readout from the AMS 5915 is always initiated by a start condition. Stop P (stop condition) The stop condition is always generated by the I²C -master after a data transfer has been completed. The stop condition is defined as a transition from “low level” to “high level” on the SDA line while the SCL line is still on “high level”. The digital data readout from the AMS 5915 is always terminated by a stop condition. Valid data Data is transmitted in bytes (8 bits), starting with the most significant bit (MSB). O ne data bit is transmitted with each clock pulse. The transmitted bits are only valid when, following a start condition, the level on the SDA line is constant as long as the SCL line is on “high level”. Changes to t he SDA level must be made while the SCL line is on “low level”. Acknowledge A After a byte has been transmitted the respective receiver (master or slave) has to send a n acknowledge (additional acknowledge bit) confirming the correct receipt of the data. For this purpose the master generates an extra acknowledge-related clock pulse. The receiver sends the acknowledge bit by pulling the SDA line down to “low level” during the additional clock pulse. Addressing / Slave address (I²C-address AMS 5915) After the start condition the master sends an addressing byte (the first by te after the start condition) which determines which slave is selected. The addressing byte contains the individual 7 -bit slave address of the selected slave (AMS 5915) and a data direction bit (R/ W ). A "0" for the R/ W bit indicates a transmission from master to slave (W: write; the master wishes to transmit data to the selected slave), a "1" a data request (R: read; the master requests data from the slave). The pressure sensors in the AMS 5915 series have a factory -programmed 7 -bit slave address of 0x28 Hex (0101000bin), which is stored in the sensor’s EEPROM. On request each AMS 5915 can be ordered with an individual 7-bit slave address programmed at the factory. Using AMS 5915’s USB starter kit the customer can program the individual slave address himself. In general 7-bit addressing allows 128 different addresses. If more than one AMS 5915 should be connected to the same I²C-bus, each pressure sensor requires an individual slave address.
Board Mount Pressure Sensor AMS 5915 SERIES © 2023, Analog Microelectronics GmbH www.analog-micro.com Datasheet AMS 5915 – Rev. 4.1 10/15 DATA READOUT VIA THE I2C-INTERFACE The digital output values for pressure (14 -bit value) and temperature (11 -bit value) are read from AMS 5915’s output register via AMS 5915’s I²C-interface. The data readout, which is illustrated in Figure 4, is done byte by byte. A data request from the I²C -master always initializes the data transfer via the I²C -bus. For this purpose the I²C-master generates a start condition on the I² C-bus lines. Following the start condition the I²C -master then sends the addressing byte containing the 7 -bit slave address of the AMS 5915 (programmed to 0x28Hex = 0101000 bin at the factory) and the data direction bit R = 1 which indicates a data request . The selected pressure sensor first answers with an acknowledge bit. The selected sensor then starts the data transfer from the output register. For pressure and temperature value readout four data bytes are transmitted from the pressure sensor to the I²C-master. The two bytes for the current digital pressure value are sent first, followed by the two bytes for the current digital temperature value, always beginning with the most significant byte. On each transferred data byte the I²C -master sends an ackno wledge bit confirming the correct receipt of data. After the fourth data byte, the receiving master generates a no acknowledge bit and the pressure sensor is set to inactive. The I²C-master shuts down the data transfer by sending a stop condition. The last 6 bits of the first data byte and the 8 bits of the second data byte always beginning with the most significant bit give the 14 -bit pressure value. The 8 bits of the third data byte and the first 3 bits of the fourth data byte give the 11-bit temperature value. For pressure value readout only it is possible to stop the data transfer after two data bytes. In this case the I²C-master sends a no acknowledge bit after the second data byte and shuts down the data transfer by sending a stop condition.

Board Mount Pressure Sensor AMS 5915 SERIES © 2023, Analog Microelectronics GmbH www.analog-micro.com Datasheet AMS 5915 – Rev. 4.1 11/15 Calculating the current pressure and temperature value The digital output values for pressure (14 -bit value) and temperature (11 -bit value) have to be converted in order to generate the desired information on pressure and temperature in physical units. The curr ent pressure in mbar (or PSI) is calculated from the digital pressure value using the following equations: pp = Digoutp(p) − Digoutpmin Sensp + pmin with SSensp = Digoutpmax − Digoutpmin pmax − pmin (1) wherein p is the current pressure in mbar 2, pmin is the specified minimum pressure and pmax is the specific maximum pressure in mbar; depending on the s pecified pressure range, Digoutp(p) is the current digital 14- bit pressure value in counts, Digoutpmin and Digoutpmax are the digital pressure values at minimum and maximum specified pressure in counts and Sensp is the sensitivity of the pressure sensor in counts/mbar. The current sensor temperature in °C is calculated from the digital temperature output val ue using the following equation: TT = DigoutT(T) 2048 ∗ 200 °C − 50 °C (2) Therein T is the current sensor temperature in °C and DigoutT(T) is the current 11 -bit digital temperature output value in counts. Example: At the digital output of an AMS 5915-0005-D-B (-5 … 5 mbar bidirectional differential sensor) the following data bytes 1 … 4 are read: Byte 1: 00101100 Byte 2: 11001101 Byte 3: 01011100 Byte 4: 11100000 Taking the last 14 bits of byte 1 and byte 2 the current 14 bit digital pressure value is: Digoutp(p) = 10110011001101bin counts = 2CCDHex counts = 11469Dec counts and with the first 11 bits of byte 3 and byte 4 the digital temperature value is: DigoutT(T) = 01011100111 bin counts = 2E7Hex counts = 743Dec counts. For AMS 5915-0005-D-B the following values are specified: pmin = -5 mbar, pmax = 5 mbar and Digoutpmin = 1638, Digoutpmax = 14745 Using these values and equation (1) the current pressure in mbar can be calculated: pp = (11469 − 1638) counts (13107 / 10) counts / mbar + (-5) mbar = 2.501 mbar Using equation (2), the current sensor temperature in °C is calculated as: TT = (743 ∙ 200) counts∙°C 2048 counts − 50 °C = 22.6 °C 2 If the current pressure is required in another physical unit, we suggest calculating the current pressure value in mbar as described above and converting the value into the required physical unit then.
