AD9747BCPZ

AD9747 is a pin-compatible, high dynamic range, dual DAC with 16-bit resolutions and sample rates of upto 250MSPS. This device include specific features for direct conversion transmit applications, including gain and offset compensation, and they interface seamlessly with analogue quadrature modulators, such as the ADL5370. A proprietary, dynamic output architecture permits synthesis of analogue outputs even above Nyquist by shifting energy away from the fundamental and into the image frequency. A serial peripheral interface (SPI) port provides full programmability. In addition, some pin-programmable features are offered for those applications without a controller. It is widely used in application such as wireless infrastructure W-CDMA, CDMA2000, TD-SCDMA, WiMAX, wideband communications: LMDS/MMDS, point-to-point, instrumentation, radio frequency (RF) signal generators, arbitrary, waveform generators etc.
