双12位/ 14位/ 16位, LVDS接口, 500 MSPS数模转换器 Dual 12-/14-/16-Bit, LVDS Interface, 500 MSPS DACs
GENERAL DESCRIPTION
The AD9780/AD9781/AD9783 include pin-compatible, high dynamic range, dual digital-to-analog converters DACs with 12-/14-/16-bit resolutions, and sample rates of up to 500 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. Some pin-programmable features are also offered for those applications without a controller.
