Analog Devices AD1877 16‑Bit Stereo ADC Datasheet
The AD1877 is a stereo, 16‑bit oversampling ADC based on Sigma‑Delta technology, intended for digital audio applications. It operates from a single 5 V supply, provides up to 92 dB dynamic range, and features a flexible serial interface that can operate in master or slave mode.
Key features include a fourth‑order one‑bit modulator, a three‑stage FIR decimation filter with 64× oversampling, on‑chip voltage reference, and single‑ended to differential converters. The device requires four external 470 pF NPO filter capacitors and supports input clocks of 12.288 MHz (256×FS) or 18.432 MHz (384×FS).
