DESCRIPTION

The PCM1690 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.

Hardware Control

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
