GENERAL DESCRIPTION

The AD9741/AD9743/AD9745/AD9746/AD9747 are pin compatible, high dynamic range, dual digital-to-analog converters (DACs) with 8-/10-/12-/ 14-/16-bit resolutions and sample rates of up to 250 MSPS. The devices include specific features for direct conversion transmit applications, including gain and offset compensation, and they interface seamlessly with analog quadrature modulators, such as the ADL5370.
