Note 6: These specifications apply for VS=±15V and Ground pin at ground, and -55°C < TA < +125°C, 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.
Note 7: The offset voltages and offset currents given are the maximum values required to drive the output within a volt of
either supply with a 1mA load. Thus, these parameters define an error band and take into account the worst-case effects of
voltage gain and RS.
Note 8: The response time specified (see definitions) is for a 100 mV input step with 5 mV overdrive.
Note 9: This specification gives the range of current which must be drawn from the strobe pin to ensure the output is properly
disabled. Do not short the strobe pin to ground; it should be current driven at 3 to 5 mA.
