General Description
The HT82V738 is a high performance audio DAC converter. It provides digital de-emphasis (32, 44.1 and 48kHz), external mute control and adjustment for serial data and clock. The HT82V738 accepts data at audio rates up to 96kHz. It performs within a wide dynamic range, high SNR ratio and has low clock jitter sensitivity. HT82V738 is an ideal DAC for DVD players, MP3 players and set-top box systems. It is also pin-compatible with CS4340.
