The LM324N features four independent, high gain, operational amplifiers in a single package, that operate from a single power supply (from 3V up to 32V). You can use a single OpAmp or all four.

These OpAmps are widely used and should cover most of your project needs.

Features

• Internally frequency compensated for unity gain
• Large DC voltage gain: 100dB
• Wide power supply range: 3V~32V (or ±1.5 ~ 16V)
• Input common mode voltage range includes ground
• Large output voltage swing: 0V to VCC -1.5V
• Power drain suitable for battery operation
• 0.4V/uS slew rate
• Low power: quiescent current is 430-μA/amplifier at 5 V
