What is the maximum output voltage (Vom) of an operational amplifier?

Latest Updated:12/01/2011

Question:

What is the maximum output voltage (Vom) of an operational amplifier?

Answer:

This expresses the limit value at which the output of the operational amplifier is saturated when the prescribed power supply voltage is applied. There are two values: one for the positive power supply side and one for the negative power supply side. In addition, either a load resistance value (2 kΩ, 10 kΩ) between the output pin and GND or the output current must be set. The maximum output voltage refers to the dynamic area beyond which the output is saturated in the positive or negative direction, and is limited according to the load resistance value. It may vary depending on the operational amplifier type, but usually the maximum output voltage falls within the range of a voltage 1 V to 1.5 V lower than V+ to a voltage 1 V to 1.5 V higher than V-. Be aware, therefore, that when the power supply voltage (V ±) changes, the maximum output voltage will also change.
