* Tlow=- 25 C corresponds to lm 211, and tlow = 0 c corresponds to LM311.

* Thigh=85 C corresponds to lm 211, and Thigh = 75 c corresponds to LM311.

NOTES:1. The specifications of offset voltage, offset current and bias current correspond to the power supply voltage of 5V

to ±15V.

2. This rating is for the case of ±15V power supply. The positive input voltage limit is 30V higher than the

negative power supply,and the negative input limit is equivalent to the negative power supply voltage, or

30V lower than the power supply, or whichever is smaller.

3.

Given offset voltage and offset current, it is required to drive a load with a maximum value of 1mA in any

power supply voltage range, and these parameters define the error range, thus taking the worst case of

voltage gain and input impedance into account.

4.

The specified response time is 100Mv input plus 5MV overdrive signal.

5.

Don't directly ground the STROBE pin, it needs to be driven by 3mA~5mA current.
