DESCRIPTION
●The DSD1794A 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.
