Response Time – (note 3)
1. For supply voltages less than
±
15V the absolute maximum input voltage is equal to the supply voltage.
2. These specifications apply for V
CC
=
±
15V, unless otherwise stated. The offset voltage, offset current and
bias current specifications apply for any supply voltage from a single +5V supply up to
±
15V supplies.
The offset voltages and offset current given are the maximum values required to drive the output down to 1V
or up to +14V with a 1mA load current.
Thus, these parameters define an error band and take into account the worst case effects of voltage gain
and input impedance.
3. The response time specified is for a 100mV input step with 5mV overdrive.
