    The ADPD103 is a highly efficient photometric front end with an integrated 14-bit analog-to-digital converter (ADC) and a 20-bit burst accumulator that works in concert with flexible light emitting diode (LED) drivers. It is designed to stimulate an LED and measure the corresponding optical return signal. The data output and functional configuration occur over a 1.8 V I2C interface. The control circuitry includes flexible LED signaling and synchronous detection.


    The analog front end (AFE) features best-in-class rejection of signal offset and corruption due to modulated interference commonly caused by ambient light.


    Couple the ADPD103 with a low capacitance photodiode of <100 pF for optimal performance. The ADPD103 can be used with any LED.


    Aplications

    • Body worn health and fitness monitors, for example, heart rate monitoring
    • Clinical measurements, for example, SpO2
    • Industrial monitoring

    Product Detail

    The EVAL-ADPD103Z-GEN evaluation board provides the user with a simple means of connecting their own optics to the ADPD103 photometric front end to evaluate the ADPD103 in a number of different applications, from vital signs monitoring to industrial sensing. The evaluation board includes the OpenMarket WaveTool graphical user interface (GUI) that provides the user with low level and high level configurability, real-time frequency and time domain analysis, and User Datagram Protocol (UDP) transfer capability so that the evaluation board can easily interface to the user’s development system.


    The USB port powers the EVAL-ADPD103Z-GEN. On-board voltage regulators provide voltage supplies for the ADPD103, ADuCM360, and FTDI Chip FT232. There are on-board regulators that provide 3.3 V and 4.3 V LED supplies, as well as a selectable option to add an external LED supply. The evaluation board provides an LED and photodiode (PD) for a finger photo-plethysmography (PPG) measurement that is useful for a quick functionality check of the evaluation system.


    The schematic and board layout, as well as the board itself, indicate signal names for easy identification. For additional information on the functionality of the ADPD103, refer to the ADPD103 datasheet.
