24-bit 192kHz Stereo Audio DAC
DESCRIPTION
The AV2636 is a high performance, low power
stereo audio digital to analog converter (DAC). It
is designed for high performance audio
applications such as CD player, DVD player,
home theater systems, digital TVs and set top
boxes. Based on the state of the art multi-bit
Σ
modulator, it also includes the digital
interpolation filters, digital volume control, digital
de-emphasis and analog low pass filters. It has
no linearity drift due to time and temperature. It
also has high tolerance to clock jitter.
The device has a serial audio interface that
accepts 16/18/20/24 digital data in I
2
S, Right-
justified or DSP mode. It can work at auto-detect
mode or programmable mode with a two-wire
serial command interface. Audio sample rates
from 8kHz to 192kHz are supported.
