PCM1780DBQ

The PCM1780DBQ is a CMOS monolithic stereo Digital-to-analog Converter (DAC) supports circuitry. The data converter use TIs enhanced multilevel delta-sigma architecture to achieve excellent dynamic performance and improved tolerance to clock jitter. The PCM1780 accepts industry standard audio data formats with 16 to 24-bit data, providing easy interfacing to audio DSP and decoder chips. Sampling rates up to 200kHz are supported. The PCM1780 provides a full set of user-programmable functions through a 3-wire serial control port, which supports register write functions. The PCM1781 provides a subset of user-programmable functions through four control pins.
