Product Summary
The PCM1770PWR is a CMOS, monolithic, integrated circuit which includes stereo digital-to-analog converters, headphone circuitry, and support circuitry in small TSSOP-16 and VQFN-20 packages. The PCM1770PWR accepts several industry standard audio data formats with 16- to 24-bit data, left-justified, I2S, etc., providing easy interfacing to audio DSP and decoder device. 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.
