What is Dual Power Supply? – Circuit Construction and Working
1. The need for a Dual power supply in OPAMPS. OPAMPS generally need to swing bipolar output voltages. One of them goes either in positive or in negative in response to the normal input signal range. Thus OPAMPS has two rails. So in order to provide power to the OPAMPS, we need a Dual power supply. 2. The need for a Dual power supply in Generators
