Description
The AD12250A converts stereo single-ended analog
input signals into 24-bit I²S digital audio data
through on-chip anti-aliasing filter, multi-bit Σ-Δ
modulator, decimation filter and high-pass filter
which removes dc offsets. The AD12250A supports
sampling frequencies from 8 kHz to 96 kHz and
offers 128 F_S, 256 F_S, 384 F_S or 512 F_S system clock
operation modes depending on sampling frequency
and master/slave mode selection. The AD12250A is
suitable for digital audio media applications which
require high performance A/D conversion and low
system cost.
