DESCRIPTION
The PCM1789-Q1 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-Q1 supports a 24-bit, DSP format in
addition to I2S, left-justified, and right-justified
formats.
The PCM1789-Q1 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-Q1 is available in a 24-pin
TSSOP package.

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.
