LM324 Quad OP-AMP IC Pinout, Circuit, Datasheet, and Uses

LM324 Quad Op-Amp IC:

The LM324 is a quad operational amplifier (op-amp) IC that contains four independent op-amps. Below is an overview of its pinout, typical circuit configuration, resources such as datasheets, and common uses:

Pinout:

The LM324 typically comes in an 14-pin package (e.g., DIP or SOIC). Each op-amp within the IC has its inputs and outputs. The pinout for each op-amp is as follows:

  1. Inverting Input (-)
  2. Non-Inverting Input (+)
  3. Output
  4. V- (Negative Power Supply Pin)
  5. OutA (Output of Op-Amp A)
  6. Inverting Input A (-)
  7. Non-Inverting Input A (+)
  8. V+ (Positive Power Supply Pin)
  9. OutB (Output of Op-Amp B)
  10. Inverting Input B (-)
  11. Non-Inverting Input B (+)
  12. NC (Not Connected)
  13. OutC (Output of Op-Amp C)
  14. Inverting Input C (-)

Circuit Configuration:

A typical inverting amplifier circuit using one of the op-amps in the LM324 could look like this:
