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.
