In previous articles—Common op-amp circuits, Op amps do integration, and The practical op-amp differentiator is quite versatile—we looked at some classic op amp circuits. These circuits used negative ...

For continuous-duty, high-amperage circuits Hamilton prefers to use ring terminals rather than spade connectors, since they offer a superior connection with less chance of failure.

The operational amplifier (op-amp) is a high performance gain device with essentially linear qualities.

Various techniques can reduce these errors, including inverted operating mode, dc biasing, small ac signal swing, proper selection of the op amp, and input impedance compensation.1 Matching the ...

The preceding discussions focus on a circuit's sensitivity to coupled noise, and overlook the circuit's potential for producing such noise. Current flow in a conductor produces a magnetic field ...
