DATASHEET

PORTABLE CONSUMER CODEC

LOW-POWER, HIGH-FIDELITY INTEGRATED CODEC

ACS422x68

The ACS422x68 is a low-power, high-fidelity integrated

CODEC targeted at portable applications such as tablet

computers, personal navigation devices, portable projec-

FEATURES

•

High fidelity 24-bit stereo CODEC

•

DAC 102dB SNR; THD+N better than -82dB

tors and speaker docks.

In addition to a high-fidelity
