PRODUCT DESCRIPTION

The AD9784 is a 14-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 AD9784 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.
