Operational Amplifiers Boosting Op-Amp Output Current

2020-12-10
Some applications require high output current from a precision operational amplifier (op-amp). Often, the op-amp can deliver this current, but not without sacrificing its precision performance. In this case, external transistor amplifiers can be added to boost the output current of the op-amp to the required level. While there is a wide variety of possible current amplifier options, this application note discusses the two most commonly applied solutions.
