DESCRIPTION

The PCM1602A is a CMOS, monolithic integrated

circuit that features six 24-bit audio digital-to-analog

converters (DACs) and support circuitry in a small

LQFP-48 package. The DACs use Texas Instruments'

enhanced multilevel, delta-sigma architecture that

employs fourth-order noise shaping and 8-level

amplitude quantization to achieve excellent

signal-to-noise performance and a high tolerance to

clock jitter.

The PCM1602A accepts industry-standard audio data

formats with 16- to 24-bit audio data. Sampling rates

up to 200 kHz (channels 1 and 2) or 100 kHz

(channels 3, 4, 5, and 6) are supported. A full set of

user-programmable functions is accessible through a

4-wire serial control port that supports register write

and read functions.
