Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: Differential input voltages greater than 1V will cause excessive
current to flow through the input protection diodes unless limiting
resistance is used.

Note 4: 10Hz noise voltage density is sample tested on every lot. Devices
100% tested at 10Hz are available on request.
Note 5: This parameter is tested on a sample basis only.
Optional Offset Nulling and Overcompensation
Circuits
Input offset voltage can be adjusted over a 800 V range
with a 5k to 100k potentiometer.
The LT1012 is internally compensated for unity gain
stability. The overcompensation capacitor, C
used to improve capacitive load handling capability, to
narrow noise bandwidth, or to stabilize circuits with gain
in the feedback loop.
