ADPD175GGI-ACEZ-RL

Overview

The ADPD175GGI is a complete photometric module integrating an ASIC, three LEDs, and a photodiode within a 2.8 mm × 6.5 mm package. It features a 14-bit ADC with a 20-bit burst accumulator for high-resolution signal capture. The system includes a true 3-channel LED driver capable of up to 370 mA, allowing independent configuration for each channel. Synchronous detection provides effective rejection of ambient light interference. Configuration and data output are managed via a 1.8 V I²C interface.
