Description for the PCM1690

The PCM1690 device is a high-performance, single-chip, 24-bit, eight-channel, audio digital-to-analog converter (DAC) with differential outputs. The eight-channel, 24-bit DAC employs an enhanced, multi-level delta-sigma (ΔΣ) 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 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. The PCM1690 is available in a 12-mm × 8-mm (12-mm × 6-mm body) HTSSOP-48 package.

For all available packages, see the orderable addendum at the end of the data sheet.
