Precautions should be taken to insure that the power supply
for the integrated circuit never becomes reversed in polarity
or the unit is not inadvertently installed backwards in the test
socket as an unlimited current surge through the resulting
forward diode within the IC could destroy the unit.
Application Hints
The LP324 series is a micro-power pin-for-pin equivalent to
the LM324 op amps. Power supply current, input bias cur-
rent, and input offset current have all been reduced by a fac-
tor of 10 over the LM324. Like its predecessor, the LP324 se-
ries op amps can operate on single supply, have
true-differential inputs, and remain in the linear mode with an
Large differential input voltages can be easily accommo-
dated and, as input differential voltage protection diodes are
not needed, no large input currents result from large differen-
tial input voltages. The differential input voltage may be
larger than V+ without damaging the device. Protection
should be provided to prevent the input voltages from going
negative more than −0.3 VDC (at 25˚C). An input clamp diode
with a resistor to the IC input terminal can be used.

The pinouts of the package have been designed to simplify
PC board layouts. Inverting inputs are adjacent to outputs for
all of the amplifiers and the outputs have also been placed at
the corners of the package (pins 1, 7, 8, and 14).
