† _{All typical values are at VCC± = ±15 V, TA = 25°C.}
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.
8. Voltages are with respect to EMIT OUT and V_CC− tied together.
9. The strobe should not be shorted to ground; it should be current driven at 100 μA to 300 μA.
