LM224W

1. Either or both input voltages must not exceed the magnitude of V_CC+ or V_CC-.
2. Short-circuits from the output to V_CC can cause excessive heating if V_CC > 15V. The maximum output current is approximately 40mA independent of the magnitude of V_CC. Destructive dissipation can result from simultaneous short-circuit on all amplifiers.
3. This input current only exists when the voltage at any of the input leads is driven negative. It is due to the collector-base junction of the input PNP transistor becoming forward biased and thereby acting as input diodes clamps. In addition to this diode action, there is also NPN parasitic action on the IC chip. this transistor action can cause the output voltages of the Op-amps to go to the V_CC voltage level (or to ground for a large overdrive) for the time duration than an input is driven negative.This is not destructive and normal output will set up again for input voltage higher than -0.3V.

These circuits LM224W consist of four independent, high gain, internally frequency compensated operational amplifiers. They operate from a single power supply over a wide range of voltages. Operation from split power supplies is also possible and the low power supply current drain is independent of the magnitude of the power supply voltage.

All the pins are protected against electrostatic discharges up to 2000V (as a consequence, the input voltages must not exceed the magnitude of V_CC+or V_CC-.)
