To power an op-amp with a dual supply (+Vcc and -Vcc) you can use two power supplies connected in series. I would like to find an alternative and less expensive way to do this as (in my project) the two power supplies would only power the op-amp which seems a bit wasteful.
However, since these circuits usually necessitate a ground reference, we describe Operational amplifiers as possessing dual power supplies. Since many of today's devices require lower voltages, we will examine the process of converting a single voltage into a +5 volts and -5 volts DC dual power supply.
If you need a dual power supply but only have a single one, you should build a power supply splitter circuit like this. Many op-amps have this problem: they need a split supply, with positive, negative, and ground terminals, but most power supplies have only a single output (positive and negative).
A dual supply amplifier uses ground as its reference, with a positive and a negative power supply. So I could use the same amplifier (both for display here and for simulations), a -2.5V bias was used at the input to obtain zero voltage at the output with no signal.
If you're unwilling to build the amps and supplies to take measurements, the results can be simulated. A dual supply amplifier uses ground as its reference, with a positive and a negative power supply.
Many electronic analog circuits require a dual power supply for proper functionality, and this is especially true of operational amplifier circuits. A negative voltage supply is a requirement of various digital systems as well, such as analog-to-digital converters and comparators.
