PGA2500IDB Integrated Circuit Chip Digitally Controlled Microphone Preamplifier SSOP28​

Product Description Of PGA2500IDB

PGA2500IDB is a digitally controlled, analog microphone preamplifier designed for use as a front end for highperformance audio analog-to-digital (A/D) converters.

PGA2500IDB features include low noise, wide dynamic range, and a differential signal path. An on-chip DC servo loop is employed to minimize DC offset, while a common-mode servo function may be used to enhance common-mode rejection.
