AD9786
GENERAL DESCRIPTION
The AD9786 is a 16-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 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.
