DESCRIPTION
The PCM1793 is a monolithic CMOS integrated circuit that
includes stereo digital-to-analog converters and support
circuitry in a small 28-lead SSOP package. The data
converters use TI’s advanced segment DAC architecture
to achieve excellent dynamic performance and improved
tolerance to clock jitter. The PCM1793 provides balanced
voltage outputs, allowing the user to optimize analog
performance externally. Sampling rates up to 200 kHz are
supported.
