资 源 简 介
The AD9786 is a 16-bit， high speed， CMOS DAC with 2&TImes;/4&TImes;/8&TImes; 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.
