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.
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.
