AD9782

The AD9782 is a 12-bit, high speed, CMOS DAC with 2×/4×/8× interpolation and signal processing features tuned for communications applications. It offers state of the art distortion and noise performance. The AD9782 was developed to meet the demanding performance requirements of multicarrier and third generation base stations. The selectable interpolation filters simplify interfacing to a variety of input data rates while also taking advantage of oversampling performance gains. The modulation modes allow convenient bandwidth placement and selectable sideband suppression.

The flexible clock interface accepts a variety of input types such as 1 V p-p sine wave, CMOS, and LVPECL in single ended or differential mode. Internal dividers generate the required data rate interface clocks. The AD9782 provides a differential current output, supporting single-ended or differential applications; it provides a nominal full-scale current from 10 mA to 20 mA. The AD9782 is manufactured on an advanced low cost 0.25 µm CMOS process.
