What's the rated supply voltage (V+-V-) of operational amplifiers?

Latest Updated:12/01/2011

Question:

What is the rated power supply voltage (V+-V-) of operational amplifiers?

Answer:

This is the maximum power supply voltage that can be applied between the V+ and V- pins. For example, if the rated power supply voltage is 36 V max., the following voltages can be applied.

When using a dual-power-supply device: ±18 V (asymmetrical is applicable)
When using a single-power-supply device: +36 V


Operational amplifiers do not have a GND pin, so the voltage that can be applied between the V+ and V- pins is 36 V for both dual- and single-power-supply devices. Note, however, that the device may be seriously damaged if the power supply is connected in reverse.
