Part Description: AD9741/AD9743/AD9745/AD9746/AD9747 Dual 8-/10-/12-/14-/16-Bit 250 MSPS Digital-to-Analog Converters Data Sheet (Rev. 0)


Part Details:

Dual 8-/10-/12-/14-/16-Bit 250 MSPS Digital-to-Analog Converters AD9741/AD9743/AD9745/AD9746/AD9747 FEATURES GENERAL DESCRIPTION High dynamic range, dual DACs The AD9741/AD9743/AD9745/AD9746/AD9747 are pin- Low noise and intermodulation distortion compatible, high dynamic range, dual digital-to-analog Single carrier WCDMA ACLR = 80 dBc @ 61.44 MHz IF converters (DACs) with 8-/10-/12-/ 14-/16-bit resolutions Innovative switching output stage permits useable outputs and sample rates of up to 250 MSPS. The devices include beyond Nyquist frequency specific features for direct conversion transmit applications, LVCMOS inputs with dual-port or optional interleaved including gain and offset compensation, and they interface single-port operation seamlessly with analog quadrature modulators, such as the Differential analog current outputs are programmable from ADL5370. 8.6 mA to 31.7 mA full scale A proprietary, dynamic output architecture permits synthesis Auxiliary 10-bit current DACs with source/sink capability for of analog outputs even above Nyquist by shifting energy away external offset nulling from the fundamental and into the image frequency. Internal 1.2 V precision reference voltage source Operates from 1.8 V and 3.3 V supplies Full programmability is provided through a serial peripheral 315 mW power dissipation interface (SPI) port. In addition, some pin-programmable Small footprint, Pb-free, 72-Lead LFCSP features are offered for those applications without a controller. APPLICATIONS PRODUCT HIGHLIGHTS Wireless infrastructure: 1. Low noise and intermodulation distortion (IMD) enables WCDMA, CDMA2000, TD-SCDMA, WiMAX high quality synthesis of wideband signals. Wideband communications: 2. Proprietary switching output for enhanced dynamic LMDS/MMDS, point-to-point performance. Instrumentation: 3. Programmable current outputs and dual auxiliary DACs RF signal generators, arbitrary waveform generators provide flexibility and system enhancements.
