NOTES:
5. 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.
6. Voltages are with respect to EMIT OUT and VCC – tied together.
7. The strobe should not be shorted to ground; it should be current driven at 100
