LM112 LM212 LM312 Operational Amplifiers
General Description
The LM112 series are micropower operational amplifiers
with very low offset-voltage and input-current errors at
least a factor of ten better than FET amplifiers over a
b55 C to a125 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 g2V to
g20V drawing a quiescent current of only 300 mA 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 b25 C to a85 C
temperature range instead of b55 C to a125 C The
LM312 is guaranteed over a 0 C to a70 C temperature
range
