Digital control of D/A converter determines output voltage of regulator, with FET serving as voltage-variable resistor. Applications include generation of sequence of voltages for testing components or equipment. Analog Devices MDA-10Z-110 converter generates 0-2 mA output with resolution determined by 10-bit digital input. 741 opamp transforms current to 0-6 V output for varying output of 723 regulator over range of 7-37 V at 150mA maximum.-C.
