Texas Instruments PCM1789

the pcm1789 is a high-performance single-chip 24-bit stereo audio digital-to-analog converter (dac) with differential outputs. the two-channel 24-bit dac employs an enhanced multi-level delta-sigma () modulator and supports 8 khz to 192 khz sampling rates and a 16-/20-/24-/32-bit width digital audio input word on the audio interface. the audio interface of pcm1789 supports a 24-bit dsp format in addition to i2s left-justified and right-justified formats. the pcm1789 can be controlled through a three-wire spi-compatible or two-wire i2c-compatible serial interface in software which provides access to all functions including digital attenuation soft mute de-emphasis and so forth. also hardware control mode provides two user-programmable functions through two control pins. view all in datasheet
