High-voltage digitally controlled power supply uses Motorola MC1406L 6-bit DAC and MC1466L floating voltage regulator to deliver up to 1 A of load current over output voltage that can be incremented in 63 steps of 1 V each, Digital word that controls voltage is coupled into DAC with 4N28 optoisolators. Current-amplifier output stage using Darlington connection of transistors is designed to operate from +70 V supply. -D. Aidridge and N. Wellenstein, "Designing Digitally-Controlled Power Supplies," Motorola, Phoenix, AZ, 1975, AN-703, p 6.
