Adder Using Op Amp. It is possible to perform addition and subtraction simultaneously with a single op amp using the circuit. The following figure shows the inverting adder using op amp with two inputs v1 and v2.
The summing amplifier is another type of operational amplifier circuit configuration that is used to combine the voltages present on two or more inputs into a single output voltage. We can design an op amp circuit to combine number of input signals and to produce single output as a weighted sum of input signals. But an op amp can also perform summing operation.
Let us assume currents i1 and i2 are flowing through resistances r1 and r2 respectively.
By electrical4u an op amp is an amplifier. Operational amplifiers opamp has so many interesting applications and we have already created many circuits using op amps. To study op amp as adder and subtractor circuit aic practical an operational amplifier often op amp or opamp is a dc coupled high gain electronic voltage amplifier with a differential input and usually a single ended output. An op amp based adder produces an output equal to the sum of the input voltages applied at its inverting terminal.
