A dual power supply is a regular direct current power supply. It can provide a positive as well as a negative voltage and ensures a stable power supply to the device as well as helps to prevent system damage. As many electronic circuits require a source of DC power, the need for dual power supply for certain circuits is necessary.
Virtual Ground Circuits. A common problem in analog electronics is having a requirement for a dual-voltage supply (e.g. ±5 V) but only having a single supply available, such as a battery.
