Analog Devices Inc. EVAL-ADPD4000Z Evaluation Board

Analog Devices Inc. EVAL-ADPD4000Z Evaluation Board evaluates the ADPD4000 and ADPD4001 photometric front end. The EVAL-ADPD4000Z uses a simple discrete optical design for vital signs monitoring applications, specifically wrist-based photoplethysmography (PPG). The EVAL-ADPD4000Z has three green LEDs, one infrared (IR), and one red LED. The LEDs are all separately driven, and a single 7mm² photodiode (PD) is populated on the board. The PD has no optical filter coating. However, a pin-for-pin alternative device with an IR block filter is available.
