If it's a transconductance amplifier, then the output current is proportional to a control voltage -- they are voltage-controlled current sources.Operational Transconductance Amplifiers are capable of current gain in that the output current is proportional to a control current.

The basic opamp is a voltage amplifier with extremely high gain. They are pretty much useless by themselves and only become useful when incorporated into a larger circuit that includes external components that, usually through negative feedback, causes the overall circuit to behave in a desired fashion. That overall circuit could be any of a lot of different things, among them a voltage amplifier or a current amplifier or neither of the above.Hi, maybe i know doest the op-amp work as a voltage amplfier or current amplifier or both?
Is't possible to work as a current amplifier by just using an "instrumentation amplifier"?
Only if you can't work in any number base.Your sig: Shouldn't that be 11 types of people?
