Frequently Asked Questions

What is the acceptable operating voltage range for these amplifiers?

For single supplies, the range is +3V to +30V; for dual supplies, it is ±1.5V to ±15V.

Are there any built-in protections against electrical hazards?

Yes, all pins are protected against electrostatic discharges up to 2000V (ESD).

What is the maximum safe power dissipation for these OP-AMPs?

The total specified power dissipation limit is 500 mW for models LM124W, LM224W, and LM324W.

What precautions should be taken when dealing with high voltage output?

If the supply voltage (V) is greater than 15V, short-circuits from the output to VCC can cause excessive heating. The maximum output current is approximately 40mA.
