Overview
The ADPD107BCBZR7 is a highly efficient photometric front end produced by Analog Devices Inc. This component is part of the ADPD105/ADPD106/ADPD107 family, which integrates an analog front end (AFE), a 14-bit analog-to-digital converter (ADC), LED drivers, and a timing core. It is designed to provide best-in-class ambient light rejection capability without the need for photodiode optical filters. The ADPD107 is particularly suited for applications requiring precise optical measurements and low power consumption.
