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.
