Andy recommends favorite resources for basic op amp circuits and includes a portion of TI's AN-20. Test your knowledge with ...

Removing the capacitors causes the circuit to degenerate to the inverting amplifier configuration (see Common op-amp circuits). Leaving the feedback capacitor, C2, in place creates an integrator or a ...

It is by no means a good op-amp by the standards on any era but 1964, as does not have a very high gain, has no short-circuit protection, and requires an external capacitor for frequency compensation.

Topics include: circuit analysis from dc resistive networks to networks of impedances operating in the sinusoidal steady-state; circuit simplification and the Thevenin equivalent circuit; complex ...

When operating the op amp from a single supply, us the MASTER section of the supply, connecting the supply (-) to the (-V) pin of the IC, and using this connection as the circuit common ground. Check ...

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

Yet there are some types of circuits where inherent but small op-amp error sources can’t be tolerated. As a result, precision IC op amps have been created to address these needs.

The unity-gain op amp (operational amplifier) buffer circuit is routinely used to transform high-impedance inputs into low-impedance outputs. ADC (analog-to-digital converter) voltage references are ...

The op-amps used are bit old-school FET devices, but aside from the high impedance input their performance is hardly critical. Yet another op-amp circuit to hold in reserve should you ever need to ...
