DESCRIPTION
The PCM1780/81/82 is a CMOS, monolithic, inte-
grated circuit, which includes stereo digital-to-analog
converters and support circuitry in a small 16-lead
SSOP package. The data converters use TI鈥檚 en-
hanced multilevel delta-sigma architecture to achieve
excellent dynamic performance and improved toler-
ance 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).
