Strobe Current
Response Time – (note 2)
Notes:
1. The offset voltage, offset current and bias current specifications apply for anysupply voltage froma single+5V supply up to
±
15V
supplies.
The offset voltages and offset currents givenare the maximum values required to drive the output down to +1Vor upto +14V with
a 1mA loadcurrent. Thus,these parameters define an errorband and take into account the worst-case ofvoltage gain and input
impedance.
2. The response time specified (see definitions) is for a 100mV inputstep with5mV overdrive.
