3 Description
The PCM175x-Q1 family of devices 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 PCM175x-Q1 family of devices 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-Q1 device is pin-compatible with the
PCM1748, PCM1742, and PCM1741 devices, except
for pin 5.
