3 Description
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 (ÎΣ)
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.
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.
