Exposure to any Absolute Maximum Rating condition for extended periods may affect device reliability and lifetime. 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.
