Note 1:
This rating applies for
g
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.

current specifications apply for any supply voltage from a single 5.0V supply up to
g
15V supplies.
Note 4:
The offset voltages and offset currents given are the maximum values required to drive the output within a volt of either supply with a 1.0 mA load. Thus,
these parameters define an error band and take into account the worst case effects of voltage gain and input impedance.
Note 5:
The response time specified (see definitions) is for a 100 mV input step with 5.0 mV overdrive.
Note 6:
For input voltages greater than 15V above the negative supply the bias and offset currents will increaseDsee typical performance curves.
Note 7:
This specification gives the current that 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 8:
Refer to RETSF111X for LF111H military specifications.
