Op-Amp as a current amplifier

[somf0872]

current amplifier op-amp

How the Op-Amp can be designed as a current Amplifier?

For ex. i have an Op-Amp OP213 whose max short circuit current Isc=30mA. If I want to draw 300mA from this Op-Amp, what sort of configuration should I use?

Firstly it is possible or not? If yes then pls explain how .....If no then ple let me know any other Op-Amp part number that can go upto 300mA with low offset voltage and input bias current.

Basically you have two options:

- off-the-shelf "power" opamp
**broken link removed**
**broken link removed**
.. or similar ..

- boost opamp's output current with PNP+NPN pair .. for an example see picture below ..
