DESCRIPTION

–

Zero Flag

The PCM1690-Q1 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-Q1 supports the

time-division-multiplexed (TDM) format in addition to

the standard I²S, left-justified, right-justified, and DSP

formats.

•

Flexible Audio Interface:

–

I/F Format: I²S™, Left-/Right-Justified, DSP,

TDM

–

Data Length: 16, 20, 24, 32 Bits

•

Flexible Mode Control:

–

3-Wire SPI™, 2-Wire I²C™-Compatible

Serial Control Interface, or

Hardware Control

Multi Functions via SPI or I²C I/F:

–

Audio I/F Format Select: I²S, Left-Justified,

Right-Justified, DSP, TDM

The PCM1690-Q1 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-Q1 is available in a 12-mm ×

8-mm (12-mm × 6-mm body) HTSSOP-48 package.

–

Digital Attenuation and Soft Mute

Digital De-Emphasis: 32 kHz, 44.1 kHz,

48 kHz

–

Data Polarity Control

•

Multi Functions via H/W Control:

–

Audio I/F Format Select: I²S, TDM

Digital De-Emphasis Filter: 44.1 kHz

Analog Mute by Clock Halt Detection
