SLLS853F August 2007 – January 2015 DAC5682Z
The DAC5682Z allows both complex or real output. An optional Fs/4 coarse mixer in complex mode provides coarse frequency upconversion and the dual DAC output produces a complex Hilbert Transform pair. An external RF quadrature modulator then performs the final single sideband up-conversion. The interpolation filters and complex coarse mixers efficiently provide frequency plan flexibility while enabling higher output DAC rates to simplify image rejection filtering.
The DAC5682Z is characterized for operation over the industrial temperature range of –40°C to 85°C and is available in a 64-pin QFN package. Other single-channel members of the family include the interpolating DAC5681Z and the noninterpolating DAC5681.
