Note 1: Absolute Maximum Ratings are those values beyond which the life

of a device may be impaired.

Note 2: For supply voltages less than

±15V, the maximum input voltage is

equal to the supply voltage.

Note 3: Unless otherwise noted, supply voltage equals

±15V and

VCM = 0V, TA = 25°C. The ground pin is grounded. Note that the maximum

voltage allowed between the ground pin and V+ is 18V. Do not tie the

ground pin to V– when the power supply voltage exceeds

±9V. The offset

voltage, offset current and bias current specifications apply for all supply

voltages between

±15V and 5V unless otherwise specified.

Note 4: The offset voltages and currents given are the maximum values

required to drive the output within 1V 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 input impedance.

Note 5: Response time specified is for a 100mV input step with 5mV

overdrive.

Note 6: Inputs are protected with back-to-back 5.6V zener diodes. This

limits maximum differential input voltage to

±5V if current is unlimited.

Larger differential input drive is allowed if input current is limited to

±5mA

with external resistance.
