Overview
Data Sheet Integrated Optical Module with Ambient Light Rejection and Three LEDs ADPD174GGI FEATURES 2.
8 mm × 6.
5 mm module with integrated optical components 2 green LEDs located on either side of the photodiode, 1 infrared LED, and 1 photodiode True 3-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 Custom optical package made to work under a glass window Optimized SNR for signal limited cases APPLICATIONS Optical heart rate monitoring Reflective SpO2 measurement GENERAL DESCRIPTION The ADPD174GGI is a complete photometric system designed to measure optical signals from ambient light and from synchronous reflected LED pulses.
Synchronous measurement offers best-inclass rejection of ambient light interference, both dc and ac.
The module integrates a highly efficient p...
