1.

These specifications apply for VCC = ±15V, unless otherwise stated.The offset voltage, offset current and bias current

specifications apply for any supply voltage from a single +5V 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.

2.

At output switch point, Vo

≈ 1.4V, no load, with VCC from 5V to ±15V and over the full input common-mode range.

3.

The response time specified is for a 100mV input step with 5mV overdrive.
