GENERAL DESCRIPTION
Although the circuit is interchangeable with and uses the same compensation as the LM101A, an alternate compensation scheme can be used to make it particularly insensitive to power supply noise and to make supply bypass capacitors unnecessary. The low current error of the LM108A makes possible many designs that are not practical with conventional amplifiers. In fact, it operates from 10M Ohms source resistances, introducing less error than devices like the 709 with 10K Ohms sources. Integrators with drifts less than 500 uV/sec and analog time delays in excess of one hour can be made using capacitors no larger than 1uF.
