AD9747 - Digital-to-Analog Converters

Description

The AD9743/AD9745/AD9746/AD9747 are pin-compatible, high dynamic range, dual DACs with 10-/12-/ 14-/16-bit resolutions and sample rates of up to 250 MSPS.

Features

  • High dynamic range, dual digital-to-analog converters (DACs) Low noise and intermodulation distortion Single carrier W-CDMA ACLR = 80 dBc at 61.44 MHz intermediate frequency (IF) Innovative switching output stage permits useable outputs beyond Nyquist frequency LVCMOS inputs with dual-port or optional interleaved single-port operation Differential analog current outputs are programmable from 8.6 mA to 31.7 mA full-scale Auxiliary 10-bit current DACs with source/sink capability for external offse.
