DESCRIPTION
The PCM1780/81/82 is a CMOS, monolithic,
integrated circuit, which includes stereo
digital-to-analog converters and support circuitry in a
small 16-lead SSOP package. The data converters
use TI’s enhanced multilevel delta-sigma architecture
to achieve excellent dynamic performance and
improved tolerance to clock jitter. The
PCM1780/81/82 accepts industry standard audio
data formats with 16- to 24-bit data, providing easy
interfacing to audio DSP and decoder chips.
Sampling rates up to 200 kHz are supported. The
PCM1780/82 provides a full set of
user-programmable functions through a three-wire
serial control port, which supports register write functions. The PCM1781 provides a subset of
user-programmable functions through four control
pins.
The PCM1780 is pin-compatible with the PCM1680
(8-channel DAC).
