This multiplying DAC (MDAC) reference design outputs unipolar voltages from 0 V to 2.5 V. This design does not require dual supplies to realize a unipolar, positive output voltage. This design removes the need for a negative supply rail by applying a bias voltage to the output transimpedance stage.
