The LM324 IC is derived high popular that used in many circuit diagram. Which is a package of four operational amplifiers (OP-AMP) that can be powered by a battery or other single-polarity supply(positive and negative only) over a very wide voltage range.

The four op-amps are installed in a single 14-pin package.

You can use only one of the op-amps or all four.

The current consumption is unaffected by the power supply voltage.

The specifications of LM324.

1. The power supply voltage range that they use : +3 volts to +30 volts.

2. The power supply current (minimum) that they use : 0.8 milliamperes.

3. The normal output current each op-amp (at pin-output to ground) of : 20 milliamperes typical (10 ma minimum).

4. The output current that flow from the positive supply to output-pin): 8 milliamperes typical (5 mA minimum).

5. The maximum voltage gain (typical) : 100,000. The gain is set by a feedback resistors between output-pin and inverting (-) input.

The application of LM324
The LM324 has numerous circuit application. We can use it in many projects.

Other circuits are recommended.

  1. Two LED flashing alternate Display using LM324
  2. Fuzz audio converter using LM324
