PRODUCT DESCRIPTION

The AD9786 is a 16-bit, high speed, CMOS DAC with 2×/4×/8×

interpolation and signal processing features tuned for com-

munications applications. It offers state-of-the-art distortion

and noise performance. The AD9786 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 AD9786 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 AD9786 is

manufactured on an advanced low cost 0.25 µm CMOS process.
