DESCRIPTION

lithic integrated circuits which feature six 24-bit audio

digital-to-analog converters and support circuitry in

either a LQFP-48 or MQFP-48 package. The digital-

to-analog converters utilize Burr-Brown’s enhanced

multi-level, delta-sigma architecture, which employ

4th-order noise shaping and 8-level amplitude quanti-

zation to achieve excellent signal-to-noise performance

and a high tolerance to clock jitter.

The PCM1600 and PCM1601 accept industry-stan-

dard audio data formats with 16- to 24-bit audio data.

Sampling rates up to 100kHz are supported. A full set

of user-programmable functions are accessible through

a 4-wire serial control port which supports register

write and readback functions.
