LM108/LM208/LM308 Operational Amplifiers  
General Description  
The LM108 series are precision operational amplifiers hav-  
ing specifications a factor of ten better than FET amplifiers  
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 us-  
ing capacitors no larger than 1 mF.

ed 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 by-  
pass capacitors unnecessary.

Maximum input bias current of 3.0 nA over temperature  
Offset current less than 400 pA over temperature  
Supply current of only 300 mA, even in saturation  
Guaranteed drift characteristics  
The low current error of the LM108 series makes possible  
many designs that are not practical with conventional ampli-  
fiers. In fact, it operates from 10 MX source resistances,
