Symmetrical power supply circuit electronic project
A symmetrical power supply, can be designed using this circuit diagram. This symmetrical power supply is designed using a simple operational amplifier and some classic electronic components
Resistances R1 and R2 form a high impedance voltage divider. Operational amplifier makes sure that artificial potential mass is the same as the voltage at the common point between R1 and R2. The ratio of R1 and R2 determine the relationship between the two output voltages, if R1 and R2 are identical, the two output voltages are symmetrical.
