Description

The LM108 series are precision operational amplifiers having specifications a factor of ten better than FET amplifiers over a b55ßC to a125ßC temperature range.

The devices operate with supply voltages from g2V to g20V and have sufficient supply rejection to use unregulated supplies. 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 LM108 series makes possible many designs that are not practical with conventional amplifiers. In fact, it operates from 10 MX source resistances, introducing less error than devices like the 709 with 10 kX sources. Integrators with drifts less than 500 mV/sec and analog time delays in excess of one hour can be made using capacitors no larger than 1 mF.

The LM108 is guaranteed from b55 to a125, the LM208 from b25 to a85, and the LM308 from 0 to a70.
