APPLICATION NOTE 1868
Negative Resistor Cancels Op Amp Load

Abstract: Canceling the load allows the op amp the capability for high output current while maintaining all the
other high-accuracy specifications such as very high open-loop gain, low offset voltage and current, low offset-
voltage and offset-current noise, and low distortion.


Accurate op amps are often characterized as having very high open-loop gain, low offset voltage and current,
low offset-voltage and offset-current noise, and low distortion. Conspicuously absen
