PCM1794A
Description
The PCM1794A device is a monolithic, CMOSintegrated circuit that includes stereo digital-to-analog converters (DACs) and support circuitry in a small 28pin SSOP package. The data converters use TI’s advanced segment DAC architecture to achieve excellent dynamic performance and improved tolerance to clock jitter.
