ELECTRICAL CHARACTERISTICS
Note 1: Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. 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.
