Product details

Quad op-amp in a 14-SOIC — the BOM-fit baseline

The LM324KDR is a quad general-purpose operational amplifier from Texas Instruments, packaged in a 14-SOIC (3.90 mm width) for surface-mount assembly.

Operates from a single or split supply spanning 3 V to 30 V. Total quiescent current is 1.4 mA for all four channels — 350 µA per amplifier — keeping the thermal load low in the 14-SOIC package.

Input offset and bias — what to expect

These are not precision numbers — the LM324 is a workhorse for non-critical loops where a few millivolts of offset do not break the system.

Frequently asked questions

What are the exact specifications of LM324KDR?

Quad general-purpose op-amp in a 14-SOIC package.

What is the closest pin-compatible replacement for LM324KDR?

The generic LM324 in a 14-SOIC package (e.g., LM324DR from TI or LM324DT from ST) is the closest functional drop-in. Confirm the exact package code and date code for your BOM — the LM324KDR suffix indicates a specific reel and packing variant that may differ from standard LM324DR.
