Quad operational amplifier LM324N
This operational amplifier IC has a total of four operational amplifiers that use a common Vcc+ and a common Vcc-. This means that you only need one power source for the Vcc of the operational amplifiers. Below is a schematic of the pinout of the IC to help you set it up the correct way.
Technical specifications:
Max Vcc | +-16V or 23V |
Min input voltage | -0.3V |
Max input voltage | 32V |
Max output current | 70mA |
