AD9783BCPZ

AD9783BCPZ is a pin-compatible, high dynamic range, dual digital-to-analogue converter (DAC) with 16bit resolution, and sample rates of upto 500MSPS. This device includes 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 the synthesis of analogue 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. It is used in applications such as wireless infrastructure, W-CDMA, CDMA2000, TD-SCDMA, WiMAX, wideband communications, LMDS/MMDS, point-to-point, RF signal generators, arbitrary waveform generators, etc.
