DESCRIPTION
The PCM1600
(1)
and PCM1601
(1)
are CMOS mono-
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.
