The PCM1794A-Q1 device is a monolithic, CMOS-integrated circuit that includes stereo digital-to-analog converters (DACs) and support circuitry in a small 28-pin SSOP package. The data converters use TI’s advanced segment DAC architecture to achieve excellent dynamic performance and improved tolerance to clock jitter. The PCM1794A-Q1 device provides balanced current outputs, allowing the user to optimize analog performance externally. Sampling rates up to 200 kHz are supported.
