DESCRIPTION
The PCM1608 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 utilize Texas Instrument’s enhanced multi-level, 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 PCM1608 accepts industry-standard audio data formats
S
with 16- to 24-bit audio data. Sampling rates up to 200kHz
(channels 1, 2, 7, and 8) or 100kHz (channels 3, 4, 5, and 6)
are supported. A full set of user-programmable functions are
accessible through a 4-wire serial control port that supports
register write and read functions.
