16-Bit Low-Power Stereo <strong>Audio</strong> DAC with Analog<br />
Input, Headphone, Class-D Speaker Amp<br />
PCM1777<br />
<strong>Audio</strong> DACs are used in applications ranging from MP3, DVD and CD<br />
players to professional-grade PC audio interfaces and AV receivers.<br />
Functions such as headphone amplifiers and audio processors are<br />
often integrated into the audio DAC.<br />
The PCM1777 is a low-power stereo DAC that integrates stereo<br />
Class-D speaker amplifiers. It also offers multiple audio functions such<br />
as programmable gain control and a sound effects processor. It is pinfor-pin-compatible<br />
and control-register-compatible with the PCM3793<br />
and PCM3794 stereo codecs, simplifying product family designs.<br />
