What Is an Amp? Amperage measures the rate that current flows through an electrical circuit. If voltage is like water pressure, amperage is like the rate of water flow.

Andy recommends favorite resources for basic op amp circuits and includes a portion of TI's AN-20. Test your knowledge with our op amp quiz; answer explanations are included.

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

The op-amp circuit in question. He starts with the current source, a simple circuit of two diodes, a resistor, and a transistor that sets the bias for the two-transistor differential amplifier.

The circuit shown in Figure 5 is quite versatile. Removing the capacitors causes the circuit to degenerate to the inverting amplifier configuration (see Common op-amp circuits). Leaving the feedback ...

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.

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 ...
