The ● denotes specifications which apply over the full operating
temperature range.
Note 1: For supply voltages less than ±15V, the maximum input voltage is
equal to the supply voltage.
Note 2: Unless otherwise noted, supply voltage equals ±15V and
T
A
= 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 3: 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 4: Response time specified is for a 100mV input step with 5mV
overdrive.
Note 5: 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.
