Description

The PCM1794 is a monolithic CMOS integrated circuit thatincludes stereo digital-to-analog converters and supportcircuitry in a small 28-lead SSOP package.

The dataconverters PCM1794 use TI's advanced segment DAC architectureto achieve excellent dynamic performance and improvedtolerance to clock jitter. The PCM1794 provides balancedcurrent outputs, allowing the user to optimize analogperformance externally. Sampling rates up to 200 kHz aresupported.
