1. Offset voltage, offset current and bias current specifications apply for a supply voltage range from a single 5.0 V supply up to

±15 V supplies.

2. 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.

3. 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.

4. The response time specified is for a 100 mV input step with 5.0 mV overdrive.

5. Do not short the strobe pin to ground; it should be current driven at 3.0 mA to 5.0 mA.
