Working principle: the whole circuit is shown as the figure. The power input part is a common transformer buck bridge rectifier, increasing the capacitor filter can get ± 22V DC symmetrical voltage. Another two ± 6.8V auxiliary voltagea are also derived to add on IC4 and op amp IC3's V + and V-terminals to ensure that IC3 and IC4 working voltage does not exceed the limits.

The circuit is divided into two parts, one part is the regulator circuit, the other part is a digital decoder circuit. Integrated regulator block is based on LM317 adjustable regulator to matched with the corresponding partial pressure resistor, then it can get eight blocks of voltage outputs. In order to reduce the power consumption of LM317, transformer uses the center tap. When the output voltage is below 9V, it uses 12V AC voltage; When the output voltage is above 12V, it uses 24V AC voltage, and the voltage is automatically switched by relay.
