LM112/LM212/LM312 Operational Amplifiers  
General Description  
The LM112 series are micropower operational amplifiers  
with very low offset-voltage and input-current errorsÐat  
least a factor of ten better than FET amplifiers over a  
known to suffer catastrophic failure caused by short-dura-  
tion overvoltage spikes on the supplies. Unlike other inter-  
nally-compensated IC amplifiers, it is possible to overcom-  
pensate with an external capacitor to increase stability mar-  
gin.

series, that also use supergain transistors, they differ in that  
they include internal frequency compensation and have pro-  
visions for offset adjustment with a single potentiometer.  
The LM212 is identical to the LM112, except that the LM212

formance is not appreciably affected over this range of volt-  
ages, so operation from unregulated power sources is easily

The LM112 series are the first IC amplifiers to improve reli-
