NOTES:
1. This rating applies for
±
15 V supplies. The positive input voltage limit is 30 V above the negative supply. The negative input voltage limit is
equal to the negative supply voltage or 30 V below the positive supply, whichever is less.
2. These specifications apply for V

C. The offset voltage, offset current, and bias current specifications apply for any supply voltage from a single 5 V
supply up to
±
15 V 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 1 mA
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 100 mV input step with 5 mV over-drive.
5. Do not short the strobe pin to ground; it should be current driven at 3 mA to 5 mA.
6. LM311B, all parameters are at V+ = 3 V
±
10%; V– = GND = 0 V.
