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 4thorder

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 userprogrammable

functions that are accessible through a

three-wire serial control port that supports registerwrite

functions.

The PCM1753 is pin compatible with the PCM1748,

PCM1742, and PCM1741, except for pin 5.
