You think of op amps as amplifiers because, no kidding, it is right in the name. But just like some people say, “you could do ...

This chapter introduces active filters, which use operational amplifiers (op amps) to achieve better performance and flexibility in signal processing.

The WEAOPSLO18NI18RO12M22G is a special purpose low offset and low noise opamp. The opamp architecture is two-stage Miller with RC compensation. The opamp provides current outputs that copy the ...

This circuit makes use of negative feedback to ensure that the ripple signal is an exact replica of the signal applied on the non-inverting terminal of the op-amp. It works well for even square wave ...

with a popular choice being headphone amplifiers that use a tube as a gain stage followed by an op-amp as a buffer with a low impedance output. This forms the basis of [Ratti3]’s amplifier ...
