DESCRIPTION

•

Flexible Audio Interface:

The PCM1789 is a high-performance, single-chip,

24-bit, stereo, audio digital-to-analog converter (DAC)

with differential outputs. The two-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

PCM1789 supports a 24-bit, DSP format in addition

to I²S, left-justified, and right-justified formats.

–

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

Data Length: 16, 20, 24, 32 Bits

•

Flexible Mode Control:

–

3-Wire SPI™, 2-Wire I²C™-Compatible

Serial Control Interface, or

Hardware Control

–

Connect Up To 4 Devices on One SPI Bus

Multi Functions via SPI or I²C I/F:

The PCM1789 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. Also, hardware control

mode provides two user-programmable functions

through two control pins. The PCM1789 is available

in a 24-pin TSSOP package.

–

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

Right-Justified, DSP

–

Digital Attenuation and Soft Mute

Digital De-Emphasis: 32 kHz, 44.1 kHz,

48 kHz

–

Data Polarity Control

Power-Save Mode

•

Multi Functions via Hardware Control:

–

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

Digital De-Emphasis Filter: 44.1 kHz

Analog Mute by Clock Halt Detection
