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.
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.
NOTE: (1) The PCM1604 and PCM1605 utilize the same die and are
electrically identical. All references to the PCM1604 apply equally to
the PCM1605.

Pin 39 (SCKO). (4) Analog performance specifications are tested with Shibasoku #725 THD Meter 400Hz HPF, 30kHz LPF on, average mode with 20kHz
bandwidth limiting. The load connected to the analog output is 5kΩ or larger, AC-coupled. (5) SNR is tested with Infinite Zero Detection off. (6) SCKO is disabled.

ELECTROSTATIC
DISCHARGE SENSITIVITY
This integrated circuit can be damaged by ESD. Burr-Brown
recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling
and installation procedures can cause damage.
ESD damage can range from subtle performance degradation
to complete device failure. Precision integrated circuits may
be more susceptible to damage because very small parametric
changes could cause the device not to meet its published
specifications.
