Figure 1 shows a voltage follower with one QOA and with offset adjust. Figure 1. Circuit of DC buffer-follower with paralleled QOA and with external offset adjust The four OAs are paralleled and the ...
An op-amp operates on analog input. It can be used to amplify or attenuate this input, and to carry out mathematical operations such as addition, subtraction, integration, and differentiation. Because ...
In a balanced op-amp circuit, the op-amp inputs see equal impedances looking into the circuit. Balanced circuits provide better performance by cancelling some input errors and have a simple R F /R I ...
