SNOSC16B – MAY 2004 – REVISED SEPTEMBER 2004

These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam

during storage or handling to prevent electrostatic damage to the MOS gates.

This input current will only exist when the voltage at any of the input leads is driven negative. It is due to the collector-base junction of

the input PNP transistors becoming forward biased and thereby acting as input diode clamps. In addition to this diode action, there is

also lateral NPN parasitic transistor action on the IC chip. This transistor action can cause the output voltages of the op amps to go to

normal output states will re-establish when the input voltage, which was negative, again returns to a value greater than

−0.3V (at 25°C).

For operating at high temperatures, the LM324-N/LM324A/LM2902-N must be derated based on a +125°C maximum junction

temperature and a thermal resistance of 88°C/W which applies for the device soldered in a printed circuit board, operating in a still air

ambient. The LM224-N/LM224A and LM124-N/LM124A can be derated based on a +150°C maximum junction temperature. The

dissipation is the total of all four amplifiers—use external resistors, where possible, to allow the amplifier to saturate of to reduce the

power which is dissipated in the integrated circuit.

continuous short-circuits can exceed the power dissipation ratings and cause eventual destruction. Destructive dissipation can result

from simultaneous shorts on all amplifiers.
