DESCRIPTION
The PCM1753/54/55 is a CMOS, monolithic, integrated
circuit, which includes stereo digital-to-analog converters
and support circuitry in a small 16-lead SSOP package.
The data converters use TI’s enhanced multilevel
delta-sigma architecture, which employs 4th-order noise
shaping and 8-level amplitude quantization to achieve
excellent dynamic performance and improved tolerance to
clock jitter. The PCM1753/54/55 accepts industry-
standard audio data formats with 16- to 24-bit data,
providing easy interfacing to audio DSP and decoder
chips. Sampling rates up to 200 kHz are supported. A full
set of user-programmable functions is accessible through
a three-wire serial control port, which supports register
write functions.
The PCM1753/55 is pin compatible with the PCM1748,
PCM1742, and PCM1741, except for pin 5.
These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during
storage or handling to prevent electrostatic damage to the MOS gates.
