3 Description
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.
