The ideal output impedance for an operational amplifier is 0 Ω.
Crystal oscillator circuits have a very low Q.
Feedback is used in an open-loop operational amplifier circuit.
An astable multivibrator has two states.
The feedback resistor adds to the gain of an op-amp.
It takes 4 µs for the output voltage of an op-amp to rise from –14 V to +14 V. The slew rate of this op-amp is 3.5 V/µs.
In a common-mode input to an op-amp, both inputs are connected to the same signal source.
An op-amp has very low open-loop gain.
This circuit is a differentiator.
A 555 timer can be configured as an astable multivibrator.
