Part Details:

Dual 12-/14-/16-Bit, LVDS Interface, 500 MSPS DACs AD9780/AD9781/AD9783 FEATURES GENERAL DESCRIPTION High dynamic range, dual DAC parts The AD9780/AD9781/AD9783 include pin-compatible, high Low noise and intermodulation distortion dynamic range, dual digital-to-analog converters (DACs) with Single carrier W-CDMA ACLR = 80 dBc @ 61.44 MHz IF 12-/14-/16-bit resolutions, and sample rates of up to 500 MSPS. Innovative switching output stage permits usable outputs The devices include specific features for direct conversion transmit beyond Nyquist frequency applications, including gain and offset compensation, and they LVDS inputs with dual-port or optional interleaved single- interface seamlessly with analog quadrature modulators such as port operation the ADL5370. Differential analog current outputs are programmable from A proprietary, dynamic output architecture permits synthesis 8.6 mA to 31.7 mA full scale of analog outputs even above Nyquist by shifting energy away Auxiliary 10-bit current DACs with source/sink capability for from the fundamental and into the image frequency. external offset nulling Internal 1.2 V precision reference voltage source Full programmability is provided through a serial peripheral Operates from 1.8 V and 3.3 V supplies interface (SPI) port. Some pin-programmable features are also 315 mW power dissipation offered for those applications without a controller. Small footprint, RoHS compliant, 72-lead LFCSP PRODUCT HIGHLIGHTS APPLICATIONS 1. Low noise and intermodulation distortion (IMD) enable Wireless infrastructure high quality synthesis of wideband signals. W-CDMA, CDMA2000, TD-SCDMA, WiMAX 2. Proprietary switching output for enhanced dynamic Wideband communications performance. LMDS/MMDS, point-to-point 3. Programmable current outputs and dual auxiliary DACs RF signal generators, arbitrary waveform generators provide flexibility and system enhancements.
