Op Amp with Single Discrete Bipolar Transistor Output Drive

Description

Driving a low resistance load with a precision amplifier is an important requirement for many systems.  This function can be achieved with power op amps: but cost may be prohibitive.  This TI Precision design shows how to achieve high output drive capability using a precision amplifier and a simple low cost discrete bipolar transistor.
