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.
A proprietary, dynamic output architecture permits synthesis of analog outputs even above Nyquist by shifting energy away from the fundamental and into the image frequency. Full programmability is provided through a serial peripheral interface (SPI) port. In addition, some pin-programmable features are offered for those applications without a controller.
PRODUCT HIGHLIGHTS
Low noise and intermodulation distortion (IMD) enables high quality synthesis of wideband signals.
Proprietary switching output for enhanced dynamic performance.
Programmable current outputs and dual auxiliary DACs provide flexibility and system enhancements.
