DESCRIPTION
The PCM1602 is a CMOS monolithic integrated circuit
that features six 24-bit audio Digital-to-Analog Convert-
ers (DACs) and support circuitry in a small LQFP-48
package. The DACs utilize Texas Instrument’s 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 PCM1602 accepts industry-standard audio data
formats with 16- to 24-bit audio data. Sampling rates up
to 200kHz (channels 1 and 2) 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.
