NOTES:  
1. 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.  
2. These specifications apply for V =±15V and 0°C < T < 70°C unless otherwise specified. With the LM211, however, all temperature  
S
A
specifications are limited to -25°C ≤ T ≤ 85°C and for the LM111 is limited to -55°C T < 125°C. The offset voltage, offset current, and bias  
A
A
current specifications apply for any supply voltage from a single 5V supply up to ±15V supplies.  
3. The offset voltages and offset currents given are the maximum values required to drive the output within a volt of either supply with 1mA  
load. Thus, these parameters define an error band and take into account the worst case effects of voltage gain and input impedance.  
4. The response time specified is for a 100mV input step with 5mV over-drive.  
5. Do not short the strobe pin to ground; it should be current driven at 3mA to 5mA.  
6. LM311B, all parameters are at V+ = 3V ±10%, V– = GND = 0V.
