A voltage amplifier (not necessarily an op amp) has a gain of 100 V/V when its output is left open-circuited. However, when the amplifier’s output is loaded with 1.0 kΩ, the gain is only 85 V/V. The same voltage amplifier has an input impedance of 10 kΩ. If the amplifier’s output is left open-circuited but the source driving the amplifier has a Th´evenin resistance (that is, a source impedance) of 150 Ω, then the gain will be less than 100...
