Overview

Data Sheet Fully Integrated Photometric System with Ambient Light Rejection ADPD142RG/ADPD142RI FEATURES 2.
8 mm × 5 mm module with integrated optical components Red and infrared (IR) LEDs (ADPD142RI) Red and green LEDs (ADPD142RG) Photodiode True dual channel 250 mA LED driver Separate LED and AFE settings for each channel Dual data registers for each LED return signal 14-bit ADC 20-bit burst accumulator enabling 20 bits per sample period On-board sample to sample accumulator enabling up to 27 bits per data read APPLICATIONS Optical heart rate monitoring (HRM) Reflective SpO2 measurement GENERAL DESCRIPTION The ADPD142RG/ADPD142RI are complete photometric systems designed to stimulate LEDs and measure the corresponding optical return signals.
These systems feature best-in-class rejection of ambient light interference, both dc and ac.
Each module contains a highly efficient photometric front end, two LEDs, and a photodiode.
The front end consists of a control block, a 14-bit analog-...
