Using the offset null capability is easy, and often just requires the addition of a single electronic component: a potentiometer to the circuit, although in some instances digital techniques may be also employed. Here it can be of particular importance, enabling high DC gains to be employed without large offsets that can be present. The offset null connections present on many operational amplifiers chips can be used to null any small DC offsets that might appear if the capability were not used.Īlthough the op amp offset null may not be important where AC coupling is used, there are some electronic circuits where DC amplifiers are used.
