LM108A/LM208A/LM308A Operational Amplifiers  
General Description  
The LM108/LM108A series are precision operational ampli-  
fiers having specifications about a factor of ten better than  
FET amplifiers over their operating temperature range. In  
addition to low input currents, these devices have extremely  
low offset voltage, making it possible to eliminate offset ad-  
justments, in most cases, and obtain performance ap-  
proaching chopper stabilized 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.  
The LM208A is identical to the LM108A, except that the  
b
LM208A has its performance guaranteed over a 25 C to  
§
85 C temperature range, instead of 55 C to 125 C.

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.

Supply current of only 300 mA, even in saturation  
The low current error of the LM108A series makes possible  
many designs that are not practical with conventional ampli-  
fiers. In fact, it operates from 10 MX source resistances,
