The offset Voltage , offset current and bias current specifications apply for any supply Voltage from a single +5V supply up to 15V supplies.

5 The offset voltages and offset currents 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 of Voltage gain and input The response time specified is for a 100mV input step with 5mV overdrive.
