Texas Instruments DAC3282
The DAC3282 is a dual-channel 16-bit 625 MSPS digital-to-analog converter (DAC) with an 8-bit LVDS input data bus with on-chip termination, optional 2x interpolation filter, and internal voltage reference. The DAC3282 offers superior linearity, noise and crosstalk performance. The DAC3282 allows either a complex or real output.| Part No. | DAC3282 |

DESCRIPTION
Input data can be interpolated by 2x through an onchip interpolating FIR filter with over 85 dB of stopband attenuation. Multiple DAC3282 devices can be fully synchronized. An optional coarse mixer in complex mode provides frequency upconversion and the dual DAC output produces a complex Hilbert Transform pair.
