LM112/LM212/LM312 Operational Amplifiers
General Description
The LM112 series are micropower operational amplifiers
with very low offset-voltage and input-current errorsDat
least a factor of ten better than FET amplifiers over a
b
55
§
C to
a
125
§
C temperature range. Similar to the LM108
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.
These amplifiers will operate on supply voltages of
g
2V to
g
20V, drawing a quiescent current of only 300
m
A. Per-
formance is not appreciably affected over this range of volt-
ages, so operation from unregulated power sources is easily
accomplished. They can also be run from a single supply
like the 5V used for digital circuits.
The LM112 series are the first IC amplifiers to improve reli-
ability by including overvoltage protection for the MOS com-
pensation capacitor. Without this feature, IC’s have been
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.
The LM212 is identical to the LM112, except that the LM212
has its performance guaranteed over a
