DESCRIPTION
The PCM1609A 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
(TI) enhanced multilevel delta-sigma architecture that
employs fourth-order noise shaping and 8-level
amplitude quantization to achieve excellent
signal-to-noise performance and a high tolerance to
clock jitter.
The PCM1609A accepts industry-standard audio data
formats with 16- to 24-bit audio data. Sampling rates
up to 200 kHz 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.

This integrated circuit can be damaged by ESD. Texas Instruments 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.

(1) Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating
conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
