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' 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.
