In my previous article on common op-amp circuits, I mentioned that operational amplifiers were used for analog computing, where analog circuits simulated the behavior of complex systems.That article ...

In effect, this circuit is an amplitude-bounded constant-slope integrator. Figure 1 This op-amp integrator ramps up or down at a preset rate, holding a final value equal to the input-voltage dc level.

Both inverting and non-inverting op amps can be constructed from one op amp and two resistors, just in different configurations. 3. Shown is the basic design of an op-amp non-inverting circuit.

The circuit is based on a single AD8534 quad op amp chip. The first stage measures the voltage across the circuit under test in response to small current and amplifies it.

The Analog Engineer’s Circuit Cookbook: Op Amps is an example. It compiles more than 25 popular op-amp circuit designs like current sensing, attenuating, and full-wave rectifying into a single e ...
