Note 1:
The input voltage is not allowed to go more than
b
0.3V below V
b
(GND) as this will turn on a parasitic transistor causing large currents to flow through the
device.
Note 2:
Short circuits from the output to GND can cause excessive heating and eventual destruction. The maximum sourcing output current is approximately 30 mA
independent of the magnitude of V
a
. At values of supply voltage in excess of 15 V
DC
, continuous short-circuit to GND can exceed the power dissipation ratings
(particularly at elevated temperatures) and cause eventual destruction. Destructive dissipation can result from simultaneous shorts on all amplifiers.
Note 3:
For operation at elevated temperatures, these devices must be derated based on a thermal resistance of

Note 6:
Guaranteed and 100% production tested.
Note 7:
Guaranteed (but not 100% production tested) over the operating supply voltage range (3.0V to 32V for the LP124, LP324, and 3.0V to 26V for the LP2902),
and the common mode range (0V to V
a
b
1.5V), unless otherwise specified. These limits are not used to calculate outgoing quality levels.
Note 8:
The LP2902 operating supply range is 3V to 26V, and is not tested above 26V.
Note 9:
The test circuit used consists of the human body model of 100 pF in series with 1500
