LM 324

The LM324 is a quad op-amp (operational amplifier) IC, meaning it contains four independent op-amps in a single package. It is widely used in analog circuits for signal amplification, filtering, and more. 

🔧 Key Features of LM324:

• 4 Independent op-amps per package

• Wide supply voltage range: 3V to 32V (single supply) or ±1.5V to ±16V (dual supply)

• Low supply current: Typically 1 mA per amplifier

• Large voltage gain: 100 dB (typical)

• Unity-gain bandwidth: 1 MHz (typical)

• Low input bias current: 20 nA (typical)

• Common-mode input voltage: Includes ground, even when powered by a single supply
