Description

The PCM1772_1238659 are CMOS, onolithic, integrated circuits which include stereo igital-to-analog converters, lineout circuitry, and upport circuitry in small TSSOP-16 and VQFN-20 ackages.

The data converters PCM1772_1238659 use TI's enhanced multilevel - rchitecture, which employs noise shaping and ultilevel amplitude quantization to achieve excellent ynamic performance and improved tolerance to clock itter. The PCM1772_1238659 accept everal industry standard audio data formats with 16- to 4-bit data, left-justified, I2S, etc., providing easy nterfacing to audio DSP and decoder devices. ampling rates up to 50 kHz are supported. A full set of ser-programmable functions are accessible through a -wire serial control port, which supports register write unctions.
