Maxim Integrated │ 9 www.maximintegrated.com Evaluates: MAX30110 and MAX30112MAX30110 Evaluation Kit Detailed Description of Software The MAX30110 EV kit includes two sensor PCBs. Each contains a MAX30110 optical AFE, a 3-axis accelerometer together with two different photodiodes and LEDs combination. MAX30110_OSB_EVKIT comes with a discreet photodiode (TEMD5010X01) and two green LEDs (LT P4SG-V1AB-36-F), while MAX30110_SFH7050_ EVKIT comes with OSRAM SFH7050 integrated module. SFH7050 consists of an integrated photodiode and three LEDs (Red/Green/Infrared). The EV kit allows raw optical and accelerometer data to be sampled and transferred to the GUI for both dynamic viewing and logging for later analysis. The MAX30110 EV kit microcontroller PCB is used to do SPI to HID transaction translation, transporting the raw optical and accelerometer data to the PC through the USB. Most functionality of the MAX30110 has been mapped to the GUI so the wide variety of applications supported by the MAX30110 can be rapidly explored. The following is a brief description of this functionality’s options. Note that the accelerometer is operated in the 8G gain mode and its sampling rate is set to nominally match the selected sample rate of the MAX30110 with the exception of the 84sps. The two devices control sample rates internally and are inherently asynchronous. Thus the log file generated includes a sample time column that is unique for each device. Sample Rate The sample rate can take on values between 25 to 400sps. The values marked with a (2) are dual pulse modes. These are modes where the samples are unevenly spaced and averaged to improve the ambient rejection of mains line rate ambient signals. The MAX30110 can support rates up to 3.2ksps but the HID interface for the MAX30110 EV-kit has insufficient bandwidth to support rates above 400sps. Thus, these higher rates are unavailable in the MAX30110 EV kit. Low Power Mode Low power is an auto-shutdown mode that significantly reduces the average power of the AFE. This is available for all sample rates at or below 100sps. If sample rates above 100sps is selected the MAX30110 will run in regular power mode. Sample Average The MAX30110 has the capability to do sample averag - ing of 2, 4, 8, 16, and 32 samples internally. This feature is useful if more optical energy is needed to make a low perfusion measurement but the data rate across the interface or the processing power in a host micro is not desirable. This mode is also useful to further suppress the mains line noises in indoor lighting conditions. Pulse Width The pulse width setting adjusts the integration time of an exposure. The MAX30110 supports exposure integration times of 52μs, 104μs, 208μs, and 417μs. The integrated pulse width is a critical parameter in any optical measurement. Longer exposures allow for more optical photons to be integrated but also increase system power and reduce ambient rejection capability. Longer exposures also reduce the MAX30110 effective noise bandwidth and reduce the quantization step size. With a 417μs integration time, the MAX30110 quantiza - tion level equals the full-scale range/219. This quantization level reduces by a factor of two with each factor of two reduction in pulse width such that the quantization level with a 50μs integration time is full-scale range/2 16. The logged data and displayed graph continue to show a 19-bit signal range regardless of integration time. However, the LSBs at shorter pulse widths are fixed at zero. Thus with a pulse integration time of 417μs, all 19-bits are active. At 208μs pulse width, the upper 18-bits are active and the LSB is fixed at zero. At 104μs pulse width, the upper 17-bits are active and the two lower bits (B1 and B0) are fixed at zero. Finally at 52μs pulse width, the upper 16-bits are active and the lower three bits (B2, B1, and B0) are fixed at zero. ADC Full-Scale Range The MAX30110 optical channel has 4 gain ranges. When the feedback DAC (see below) is enabled, these ranges are 6μA, 12μA, 24μA, 48μA. When the feedback DAC is disabled, these ranges drop by a factor of 8 (3-bits) to 0.75μA, 1.5, 3μA, and 6μA. Feedback DAC The feedback DAC is a dynamic range extension to the native 16-bit ΔΣ ADC. When enabled, the optical ADC channel is extended to 19-bits. When disabled the opti - cal ADC channel has 16-bits of resolutions. This feature was added because virtually all the DNL in the converter comes from the feedback DAC. Thus, by disabling this DAC, one can significantly improve the DNL of the ADC with a compromise in overall dynamic range. Note that when disabling the feedback DAC, the full-scale gain ranges all divide by a factor of 8x.

Maxim Integrated │ 10 www.maximintegrated.com Evaluates: MAX30110 and MAX30112MAX30110 Evaluation Kit Add Offset Add Offset is a test option designed for dark current measurement. By adding offset to the PPG Data would allow dark current measurement without clipping the signal below 0. When Add Offset is On, an offset is added to the PPG Data to be able to measure the dark current. The offset is 8192 counts if Sample Rate is programmed for single-pulse mode. The offset is 4096 counts if PPG_SR is programmed for dual-pulse mode. AFE Supply Current Average AFE supply current is computed from the AFE settings and displayed. This is not a measured current but is computed from measured models. LED Driver Settings Each of the two LED drivers has a Range and Peak LED Current setting. There are 4 full-scale range settings 50mA, 100mA, 150mA and 200mA. Each range has an 8-bit current source DAC. The Peak LED Current box allows for an actual current to be entered. The nearest available DAC current is selected and displayed in the field. Avg LED Current The Avg LED Current field displays the average LED current based on the current AFE and LED settlings. This is a computed value based on measure characterization data. This value assumes the LED current source is fully saturated. LED Settling Time The LED Settling Time is the time prior to the start of integration (pulse-width setting) that the LED is turned on. There are four settlings, 20μs (default), 10μs, 5μs, and 2.5μs. This time is necessary to allow the LED driver to settle before integrating the exposure photo current. In practice 5μs proves to be sufficient LED settling time for low-noise applications. LED Mode Timing Slots The LED Mode Timing Slots specifies the data acquisition sequence that the internal state machine controller will follow and where the converted data will be mapped into the FIFO. Each FIFO field can be applied to one measure- ment. Acquired data can be LED1 (optical exposure from LED1 illumination), LED2 (optical exposure from LED2 illumination), LED1 and LED2 (optical exposure from LED1 and LED2 fired simultaneous), Ambient (optical data with no exposure, just ambient illumination) or None (skip this acquisition). The exposer sequence will be the entry in FIFO1 slot, FIFO2 slot, FIFO3 slot, then FIFO4 slot. This sequence will repeat for each sample instance. The data from FIFO4 Slot will not be plotted in the GUI, but will be saved to the log file. <Start Monitor>/<Stop Monitor> Button The <Start Monitor> button is used to start data acquisition from the demo. The <Start Monitor> button will only be highlighted when the MAX301100 EV-kit USB is connected and detected. Once the <Start Monitor> has been pushed the <Stop Monitor> button appears, which can be used to stop the acquisition. Once the acquisition has started, all settling are locked. Terminate the acquisition to change any settling. <Restore Defaults> Button The <Restore Defaults> button will clear out all register settlings back to the programs start up. Data Logging Raw optical and accelerometer data can be logged from the <File> pull-down menu item. When data logging is selected, the GUI asks for a filename with a default time- stamped entered into the familiar <filename> field. Enter a new filename or accept the default. Data logging will start on the next <Start Monitor> button and will continue until the <Stop Monitor> button is pressed. The final file write is only done when the <File> pull-down menu item is accessed and the data-logging button is pressed. Direct Register Write Under the <Options> pull-down menu is a direct register write button. This button opens two fields, an address and data field, below the LED Mode Timing Slots box. Any register address byte and data byte can be entered in these fields. Caution should be exercised when using this feature. Some of these registers will result in undocu- mented behavior. There is no risk of damaging the part. However, it is possible to lock up the part, requiring a power cycle induced, power on reset (unplug the USB and plug it back in again) to exit a locked-up condition.
