DESCRIPTION
The PCM1774 is a low-power stereo DAC designed
for portable digital audio applications. The device
integrates headphone amplifier, line amplifier, line
input, boost amplifier, programmable gain control,
analog mixing, and sound effects. It is available in a
small-footprint, 4-mm × 4-mm QFN package. The
PCM1774 supports right-justified, left-justified, I2S,
and DSP formats, providing easy interfacing to audio
DSP and decoder/encoder chips. Sampling rates up
to 50 kHz are supported. The user-programmable
functions are accessible through a two- or three-wire
serial control port.
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas
Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

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.
