DESCRIPTION
Sampling Frequency:
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

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.
