ADPD142RG-BCEZ-RL 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-to-digital converter (ADC) with 20-bit burst accumulator and two flexible, independently configurable LED drivers. The analog front end (AFE) handles return data from each LED on separate data paths, and with the option of separate AFE settings. The data output and functional con-figuration occur over a 1.8 V I2C interface. The control circuitry includes flexible LED signaling and synchronous detection. Applications Optical heart rate monitoring (HRM) Reflective SpO2 measurement
