I want to amplfie a +-1mA 10V signal to a +-100mA signal which op amp should I use to get this kind of a output with a voltage follower.? and will it work

 

Hi,

Go to a site that makes op amps and look up the chip you want. They will often have a search mechanism so you can search or a set of tables you can use to look up the part with the spec's you need.
There are op amps that go up to 1 amp and above.
You may not need an op amp, but you'll have to say what you are going to use this for.

There is such a thing as a transconductance amplifier, such as LM13700. A typical op amp amplifies voltage, not current. Your application sounds more like amplifying current than voltage.

 

This is one way of doing this.




Select an opamp for your output current and voltage according to MrAl's advice in post #2.

 

On re-reading the original post, is your input signal a current source limited to +/- 10v or a voltage source limited to +/- 1 ma?
