Note 4:
This rating applies for
±
15 supplies. The positive input voltage limit is 30V above the negative supply. The negative input voltage limit is equal to the
negative supply voltage or 30V below the positive supply, whichever is less.
Note 5:
The maximum junction temperature of the LM111 is 150˚C, while that of the LM211 is 110˚C. For operating at elevated temperatures, devices in the H08
package must be derated based on a thermal resistance of 165˚C/W, junction to ambient, or 20˚C/W, junction to case. The thermal resistance of the dual-in-line
package is 110˚C/W, junction to ambient.
Note 6:
These specifications apply for V
S
=
±
15V and Ground pin at ground, and −55˚C≤T
A
≤+125˚C,
unless otherwise stated. With the LM211, however, all
temperature specifications are limited to −25˚C≤T
A
≤+85˚C.
The offset voltage, offset current and bias current specifications apply for any supply voltage from a single
5V supply up to
±
15V supplies.
Note 7:
The offset voltages and offset currents given are the maximum values required to drive the output within a volt of either supply with a 1 mA load. Thus, these
parameters define an error band and take into account the worst-case effects of voltage gain and R
S
.
Note 8:
The response time specified (see definitions) is for a 100 mV input step with 5 mV overdrive.
Note 9:
This specification gives the range of current which must be drawn from the strobe pin to ensure the output is properly disabled. Do not short the strobe pin
to ground; it should be current driven at 3 to 5 mA.
Note 10:
Refer to RETS111X for the LM111H, LM111J and LM111J-8 military specifications.

Note 12:
“Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is
functional, but do not guarantee specific performance limits.”
Note 13:
This rating applies for
±
15V supplies. The positive input voltage limit is 30V above the negative supply. The negative input voltage limit is equal to the
negative supply voltage or 30V below the positive supply, whichever is less.
Note 14:
The maximum junction temperature of the LM311 is 110˚C. For operating at elevated temperature, devices in the H08 package must be derated based
on a thermal resistance of 165˚C/W, junction to ambient, or 20˚C/W, junction to case. The thermal resistance of the dual-in-line package is 100˚C/W, junction to
ambient.
