Purpose

Ideal Op-Amp with finite gain.

Op-Amps

Description

[Picture]

This Op-Amp amplifies a voltage between the non-inverting "+" and inverting "-" input with a specified gain. The resulting voltage is applied between the output and ground terminal. Output and ground are electrically isolated from the inputs. If you want to build a linear amplifier the output voltage must somehow be fed back to the inverting input. The demo models plOpAmps and plActiveLowPass demonstrate different applications with op-amps.

Open-loop gain
The voltage gain of the Op-Amp. The default is 1e6.
