2 / 22 page LM108/LM108AQML Operational Amplifiers General Description The LM108 is a precision operational amplifier having speci- fications a factor of ten better than FET amplifiers over a −55˚C to +125˚C temperature range. The devices operate with supply voltages from ±2V to ±20V and have sufficient supply rejection to use unregulated sup- plies. Although the circuit is interchangeable with, and uses the same compensation as the LM101A, an alternate com- pensation scheme can be used to make it particularly insen- sitive to power supply noise and to make supply bypass capacitors unnecessary. The low current error of the LM108 makes possible many designs that are not practical with conventional amplifiers. In fact, it operates from 10 M Ω source resistances, introducing less error than devices like the 709 with 10 k Ω sources. Integrators with drifts less than 500 µV/sec and analog time delays in excess of one hour can be made using capacitors no larger than 1 µF.
