Buffer amplifiers have unity gain. They are used to match impedances between two devices, or as isolators. Buffer amplifiers carry performance specifications such as operating temperature, input offset voltage, supply voltage, supply current and bandwidth.
Slew rate and bandwidth are also important considerations. With buffer amplifiers, slew rate at which the output voltage changes in response to a step input.
Bandwidth refers to the ability of a buffer amplifier to provide a...

Applications and UseTop
Amateur radio transmitter and receiver construction. Low power, five watts or less.
Use of amplifiers for lighting diodes led - command read relay
Note the use of impedance transformation because the digital system will not need to supply a large current.
