The offset voltages and offset currents given are the maximumvalues requiredto drive the outputdown to +1V or upto +14V with
a 1mA load current. Thus,these parameters define an errorband and take into accountthe worst-case of voltagegain and input
impedance.
2. The response time specified(see definitions) is for a 100mV input step with5mV overdrive.
