Analog Devices Inc. EVAL-ADPD4100Z-PPG Evaluation Board is designed to evaluate the ADPD4100/ADPD4101 multimodal sensor front ends. This evaluation board comes with three green LEDs, one infrared (IR) LED, and one red LED that are separately driven. The EVAL-ADPD4100Z-PPG evaluation board incorporates a single 7mm2 photodiode (PD) with no optical fiber coating. This evaluation board utilizes the Wavetool evaluation software GUI that provides low-level register access and high-level system configurability. The EVAL-ADPD4100Z-PPG evaluation board implements a simple discrete optical design for vital signs monitoring applications like wrist-based photoplethysmography (PPG).
