Source sentences:
text: Because the output impedance of the op-amp is very low, it drives the load as if it were a perfect voltage source.
text: The output impedance of the instrumentation amplifier is very low due to the difference amplifier3.
text: The output impedance is also low, being in the range of milli-ohms.
text: And the output impedance is very low: just a few ohms.
text: Often buffer amplifiers have a gain of one, i.e. they do not actually amplify, so that their output is the same amplitude as their input, but buffer amplifiers have a very high input impedance and a low output impedance and can therefore be used as an impedance matching device.
text: Modern solid state amplifiers, which use relatively high levels of negative feedback to control distortion, have extremely low output impedances
