The PCM1690DCA is a high-performance single-chip 8-channel 24-bit audio Digital-to-analog Converter (DAC) with differential outputs. The DAC employs an enhanced, multi-level delta-sigma (ΔΣ) modulator and supports 8 to 192kHz sampling rates and a 24-bit width digital audio input word on the audio interface. The audio interface of the PCM1690 supports the time-division-multiplexed (TDM) format in addition to the standard I2S, left-justified, right-justified and DSP formats. The PCM1690 can be controlled through a three-wire, SPI-compatible interface 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 a subset of user-programmable functions through two control pins.
