3 Description
The PCM1753, PCM1754, and PCM1755 (PCM175x)
devices are stereo digital-to-analog converters
(DACs) based on TI's enhanced delta-sigma
architecture. This enhanced architecture employs 4th-
order noise shaping and 8-level amplitude
quantization to achieve excellent dynamic
performance and improved clock jitter tolerance. The
PCM175x devices easily interface with audio DSP
and decoder chips because of the devices support of
industry-standard audio data formats with 16-bit and
24-bit data. The PCM175x devices can be controlled
in a hardware mode, or through a full set of user-
programmable functions that are accessible through a
three-wire serial control port that supports register-
write functions.
The PCM1753 is pin compatible with the PCM1748,
PCM1742, and PCM1741, except for pin 5.
