The two devices differ in their offset and offset drift values. The ICs are modular and their functional units individually accessible. Both ICs consist of a high-precision instrumentation amplifier for differential input signals and an operational amplifier for input signals referenced to ground. A robust reference voltage source (adjustable between 5 and 10V) can be used to power external components. An operational amplifier stage whose gain is also adjustable acts as an output. The devices also contain an additional operational amplifier which can be used as a current or voltage source. The IC is protected against reverse polarity and has an integrated output current limit. Standard industrial voltages (e.g. 0–5/10V, 0.5–4.5V) can be easily generated using transmitter ICs AM401 and AM401P.

INDUSTRIAL VOLTAGE AMPLIFIER IC AM401 analog microelectronics Mars 2006 Analog Microelectronics GmbH Phone: +49 (0)6131/91 073 – 0 7/21 An der Fahrt 13, D – 55124 Mainz Fax: +49 (0)6131/91 073 – 30 Rev. 2.3 Internet: http://www.analogmicro .de Email: info@analogmicro .de DETAILED DESCRIPTION OF FUNCTIONS AM401 is a monolithically integrated voltage transmitter which has been designed for the conditioning of differential bridge voltages and for the conversion of voltage signals referenced to ground. By varying just a few external components the output voltage can be adjusted over a wide range. All of the function blocks are individually acce ssible, enabling them to be used as functional units or, using the relevant external circuitry, conf igured as an application-specific device. Typical applications and values for external components are given in the examples described in the following. In essence AM401 consists of 4 functional blocks as shown in Figure 1. The individual blocks are as follows: 1. The core element of AM401 is its high-precision instrumentation amplifier (IA) with an internal gain of G IA and the ability to set the reference potential of the amplifier externally (pin ZA). The IA acts as an input stage for differential voltage signals. 2. There is also an operational amplifier stage (OP1). OP1’s gain of GOP1 can be set using external resistors R1 and R2 (see Figure 2). The operational amplifie r output has been designed in such a way that with certain loads it can be set down to zero. In addition, the output stage can drive up to a maximum of 10mA without an external transi stor having to be connected. An output current limit has been implemented as a protective feature which guards the IC at the output in the event of a short-circuit. 3. AM401’s voltage reference permits voltage to be supplied by external components (such as sensors, microprocessors, etc.). The reference voltage VREF has a value of either 5V or 10V. External capacitance C1 acts as a reference voltage stabilizer. It must also be connected when the voltage reference is not in use (see: Figure 2). 4. An additional operational amplifier (OP2) can be used as a current or voltage source for the supply of external components. OP2’s positive input is connected internally to voltage VBG so that the output current or voltage can be set across a wide range using one or two external resistors. Descriptions of the relevant app lications can be found on the following pages. The operational amplifier output has a sufficiently high drive power. One of AM401’s main features is its range of inte grated protective circuits which make the IC an effective output stage.

Pins VOUT, VCC and GND are protected against reverse polarity across the entire supply voltage range without the need for any additional external components.
The output of the IC is protected against short-circuiting.
All pins (with the exception of VOUT, VCC and GND) are protected by internal ESD diodes.

If OP1 is connected up as a non-inverti ng amplifier (see: Figure2) output voltage VOUT at pin VOUT is calculated as follows: 1OPINOUT GVV ⋅= with 1 1 += R RGOP where VIN is the voltage at OP1’s input pin INOP. Selecting the supply voltage In principle AM401 can be used across the entire supply voltage range defined herein. However, depending on the output voltage selected and the circuitry of the remaining components certain boundary conditions apply when selecting VCC:

When using voltage output pin VOUT the IC’s minimum supply voltage VCC necessary for the operation of the device depends on the maximum output voltage VOUTmax required by the application. The following applies: V5max +≥ OUTCC VV (6)
If the additional operational amplifier OP2 is used as a voltage reference or current source, the minimum supply voltage selected ( VCC) depends on the maximum voltage at pin CVREF. The following applies: V5max +≥ CVREFCC VV (7) When using pin VOUT and operational amplifier OP2 as a voltage reference or current source the higher value of Vcc must be set.

When operating AM401 it is imperative th at external stabilization capacitance C1 (a high-grade ceramic capacitor) is must always connected. Care must be taken that the value of the capacitance does not lie beyond its given range, even across the range of temperature (see Boundary Conditions). The maximum current drawn from the reference must not exceed a value of IREF = 10mA. 2. All of the AM401 function blocks not used by the application (e.g. OP2) must be connected up to a defined (and permitted) potential. Unused blocks, such as the additional operational amplifier (see Figure 3), must be configured. The two capacitances C1 and C2 must be connected up in any event, even if the reference voltage source is not used. 3. When OP1 is in operation the load resistance at pin VOUT must be at least 2kΩ. The values of external resistors R1, R2, R3 and R4 must be selected so th at they lie within the permitted range specified in the boundary conditions on.
