PRODUCT DESCRIPTION
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.
