General Description

The ADPD188GG is a complete photometric system designed to measure optical signals from ambient light and from synchronous reflected light emitting diode (LED) pulses.

Synchronous measurement offers best-in-class rejection of ambient light interference, both dc and ac.

The module integrates a highly efficient photometric front end, two LEDs, and two photodiode (PD).
