The op amp — short for operational amplifier — is a packaged differential amplifier. The ideal op amp — which we can’t get — has infinite gain and infinite input impedance. While we can ...

Instead it forms a pair of sample-and-hold amplifiers, alternately trimming its own offset as a differential amplifier and then trimming the offset of the other op-amp which does the amplification.

The PVOA201LN is a low power, low noise, fully-differential op amp with a rail-to-rail output and an input common-mode range including the negative power supply rail. This amplifier is an ideal ...

Differential amplifiers are used in myriad applications, including microphones, simulation, analog-to-digital conversion and automatic gain control. See op amp. THIS DEFINITION IS FOR PERSONAL USE ...
