LM324 Quad Op-Amp — Specifications & Equivalents

About the LM324

The LM324 is a Quad Op-Amp from STMicroelectronics with a supply voltage (V_CC) of +3V to +32V. It is supplied in the DIP-14 package.

At a glance

• Type: Quad Op-Amp
• Supply voltage (V_CC): +3V to +32V
• Package: DIP-14
• Manufacturer: STMicroelectronics

Typical applications

Supply headroom of +3V to +32V determines the usable output swing; allow for the device's output saturation limits when planning signal levels.

Choosing a replacement for the LM324

A drop-in substitute for the LM324 should match its polarity and offer a compatible supply range (+3V to +32V).

Mechanically, check the replacement against the DIP-14 footprint and confirm the pin order — parts sharing a package outline do not always share a pinout.

Where the application switches inductive loads or runs near the voltage limit, keep extra headroom rather than choosing a part that only just meets the original numbers.

Frequently asked questions

What is the LM324?

The LM324 is a Quad Op-Amp IC.

What package does the LM324 come in?

It is listed in DIP-14. Verify the pinout of the specific variant, as one outline can carry different pin assignments.

What can I use to replace the LM324?

This page lists 1 candidate equivalent matched on electrical ratings and package. Any replacement should meet or exceed the original voltage, current and dissipation figures and use a compatible drive level.
