DESCRIPTION
The PCM1691 is a high-performance, single-chip,
24-bit, eight-channel, audio digital-to-analog converter
(DAC) with single-ended 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
PCM1691 audio interface supports a
time-division-multiplexed (TDM) format in addition to
I²S, left-justified, right-justified, and DSP formats.
The PCM1691 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. Additionally, hardware
control mode provides two user-programmable
functions through two control pins. The PCM1691 is
available in a 12-mm × 8-mm (12-mm × 6-mm body),
48-pin HTSSOP package.
