buffer amplifier

[¦bəf·ər ′am·plə‚fī·ər]
(electronics)
An amplifier used after an oscillator or other critical stage to isolate it from the effects of load impedance variations in subsequent stages. Also known as buffer; buffer stage.

buffer amplifier

An analog device that is typically used for impedance matching and signal isolation. For example, a sound card typically uses buffer amps at most of its input and output ports.
