ANALOG DEVICES EVAL-ADPD4200Z Evaluation Board, ADPD4200, Multimodal Sensor Front End

EVAL-ADPD4200Z is an evaluation board that provides users with a simple means of evaluating the ADPD4200 photometric front end. The evaluation board implements a simple, discrete optical design for vital signs monitoring applications, specifically wrist-based photoplethysmography (PPG). The EVAL-ADPD4200Z has three green light emitting diodes (LEDs), one infrared (IR), and one red LED, which all separately driven. A single 7 mm2 photodiode is populated on the board. The photodiode has no optical filter coating. However, a pin for pin alternative device with an IR block filter is available. The full evaluation system includes the Wavetool Evaluation Software graphical user interface (GUI) that provides users with low level register access and high level system configurability. Raw data streamed to this tool can be displayed in real time with limited latency. Views are provided for both frequency and time domain analysis. The board is powered by the EVAL-ADPDUCZ microcontroller board.
