The MAX5856A integrates two 8-bit DAC cores, 4x/2x/1x programmable digital interpolation filters, phase-lock loop (PLL) clock multiplier, and a 1.24V reference. The MAX5856A supports single-ended and differential modes of operation. The MAX5856A dynamic performance is maintained over the entire power-supply operating range of 2.7V to 3.3V. The analog outputs support a compliance voltage of -1.0V to +1.25V. The 4x/2x/1x programmable interpolation filters feature excellent passband distortion and noise performance. Interpolating filters minimize the design complexity of analog reconstruction filters while lowering the data bus and the clock speeds of the digital interface. The PLL multiplier generates all internal sy...
