... These devices are capable of providing unipolar or bipolar outputs when operating from either a single +5V (MAX551) or +3V (MAX552) power supply. An internal power-on-reset circuit clears all DAC registers on power-up, setting the DAC output voltage to 0V. The SPI™/QSPI™ and Microwire™-compatible 3-wire serial interface saves board space and reduces power dissipation compared with parallel-interface devices ...
