DESCRIPTION
The LM108 is a precision operational amplifier having
specifications 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 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 makes possible
many designs that are not practical with conventional
amplifiers. In fact, it operates from 10 MΩ source
resistances, introducing less error than devices such
as the 709 with 10 kΩ 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.
