The MAX5853ETL+ is a dual, 10bit, 80Msps, current output DAC in 40 pin TQFN package. Device integrates two 10bit DAC cores and a 1.24V reference, the analogue outputs support a -1V to +1.25V compliance voltage. It can also operate in interleave data mode to reduce I/O pin count. This allows converter to be updated on a single 10bit bus. It features digital control of channel gain matching to within ±0.4dB in sixteen 0.05dB steps. Channel matching improves sideband suppression in analogue quadrature modulation applications. The on-chip 1.24V band gap reference includes a control amplifier that allows external full-scale adjustments of both channels through a single resistor. It provides superior dynamic performance in wideband communication systems and used in wireless base stations, quadrature modulation and direct digital synthesis (DDS).
