The PCM1604(1) and PCM1605(1) are CMOS mono-
lithic integrated circuits which feature six 24-bit audio
digital-to-analog converters, and support circuitry in a
small QFP-48 package. The digital-to-analog convert-
ers utilize Burr-Brown’s enhanced multi-level, delta-
sigma architecture, which employs 4th-order noise
shaping and 8-level amplitude quantization to achieve
excellent signal-to-noise performance, and a high tol-
erance to clock jitter.

Zero Detect Mute
Zero Flags May Be Used As General
Purpose Logic Outputs
The PCM1604 and PCM1605 accept industry-stan-
dard audio data formats with 16- to 24-bit audio data.
Sampling rates up to 200kHz 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.
