Description

The PCM1798 is a monolithic CMOS integrated circuit thatincludes stereo digital-to-analog converters and supportcircuitry in a small 28-lead SSOP package.

The dataconverters PCM1798 use TI's advanced segment DAC architectureto achieve excellent dynamic performance and improvedtolerance to clock jitter. The PCM1798 provides balancedcurrent outputs, allowing the user to optimize analogperformance externally. Sampling rates up to 200 kHz aresupported.
