Product details

What the 0.5V/µs slew rate means for your signal chain

The LM324KAN is a quad general-purpose op-amp from TI, packing four amplifiers into a single 14-pin DIP. Its 0.5V/µs slew rate sets a practical ceiling: a 1 V peak-to-peak sine wave starts distorting above about 80 kHz, so this is a part for audio, sensor conditioning, and DC-level shifting — not for fast ADC drivers or high-speed loops.

Single-supply workhorse, but watch the output drive

Runs on anything from 3 V to 30 V single supply, or ±1.5 V to ±15 V split. Total quiescent current for all four amps is only 1.4 mA, so it fits into a regulated 5 V rail without cooking the board.

Through-hole DIP: field-swappable, socket-friendly

The 14-DIP (0.300" width) footprint is a standard socketable package. No hot-air station needed — a technician can swap this on site with a puller and a fresh socket. The 15 nA input bias current and 2 mV input offset are typical for the LM324 family; good enough for 8-bit-level accuracy, but you will want to trim the offset for precision work.

TI lists the LM324KAN as Active. The base product number LM324 has a long production history, so supply continuity is predictable.

Frequently asked questions

What is the difference between LM324KAN and LM324N?

The KAN suffix typically indicates a tighter offset voltage specification. Pin-compatible — you can swap them on the same board if the temperature grade fits.

Can LM324KAN run on single supply?

Yes, it operates from a single 3 V to 30 V supply. The input common-mode range includes ground, so it works as a single-supply amplifier without a negative rail — common in automotive and industrial sensor interfaces.

What is the replacement for LM324KAN?

No direct replacement is listed as a successor. The LM324 family is still active. If you need a drop-in alternative, the LM324N is pin-compatible but has a narrower temperature range. For a surface-mount option, the LM324DR (SOIC-14) is functionally identical.
