Description
The AD9781BCPZ is a high-performance digital-to-analog converter (DAC) designed for direct conversion transmit applications. This device is part of the AD9780/AD9781/AD9783 series, which are pin-compatible, high dynamic range, and dual DACs with 12-/14-/16-bit resolutions, and sample rates of up to 500 MSPS. The AD9781BCPZ includes specific features such as gain and offset compensation, and interfaces seamlessly with analog quadrature modulators like the ADL5370. The device's proprietary, dynamic output architecture permits synthesis of analog outputs even above Nyquist by shifting energy away from the fundamental and into the image frequency.
