DESCRIPTION

The PCM1772 and PCM1773 devices are CMOS,

monolithic, integrated circuits which include stereo

digital-to-analog converters, lineout circuitry, and

support circuitry in small TSSOP-16 and VQFN-20

packages.

The data converters use TI鈥檚 enhanced multilevel

鈭?危

architecture, which employs noise shaping and

multilevel amplitude quantization to achieve excellent

dynamic performance and improved tolerance to clock

jitter. The PCM1772 and PCM1773 devices accept

several industry standard audio data formats with 16- to

24-bit data, left-justified, I

S, etc., providing easy

interfacing to audio DSP and decoder devices.

Sampling rates up to 50 kHz are supported. A full set of

user-programmable functions are accessible through a

3-wire serial control port, which supports register write

functions.
