NOTES:

7. The offset voltages and offset currents given are the maximum values required to drive the output within 1 V of either supply with

a 1-mA load. Thus, these parameters define an error band and take into account the worst-case effects of voltage gain and input

impedance.

9. The strobe should not be shorted to ground; it should be current driven at 100

μA to 300 μA.
