The device is an EXACT EQUIVALENT in functionality and parametrics to the compared device.
TI does not recommend using this part in a new design. This product continues to be in production to support existing customers.
The PCM1794 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 TIs advanced segment DAC architecture to achieve excellent dynamic performance and improved tolerance to clock jitter. The PCM1794 provides balanced current outputs, allowing the user to optimize analog performance externally. Sampling rates up to 200 kHz are supported.
