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.
