DESCRIPTION
The PCM1608 is a CMOS, monolithic integrated
circuit that features eight 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 ampli-
tude quantization to achieve excellent signal-to-noise
performance and a high tolerance to clock jitter.
The PCM1608 accepts industry-standard audio data
formats with 16- to 24-bit audio data. Sampling rates
up to 200 kHz (channels 1, 2, 7, and 8) 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.
