The
G
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.
