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.

TYPICAL PERFORMANCE CURVES (continued)
ANALOG DYNAMIC PERFORMANCE (continued)
All specifications at TA = 25°C, VCC = 5 V, VDD = 3.3 V, and 24-bit input data (unless otherwise noted). Conditions in 192-kHz
operation are system clock = 128 fS, DAC3 through DAC6 disabled in register 8, and oversampling rate = 64 fS (set by OVER
bit in register 12).
