Frequently Asked Questions

What are the key electrical specifications of the LM324AN/NOPB?

The LM324AN/NOPB features a maximum input bias current of 0.25 µA at 25°C, an input offset current of 0.03 µA, a typical common-mode rejection ratio of 85 dB (minimum 65 dB), and internal frequency compensation. It operates with a wide supply voltage range and is packaged in a standard Dual-In-Line (DIP) package.

What are typical applications for the LM324AN/NOPB?

The LM324AN/NOPB is used in signal conditioning, active filter design, sensor amplification, audio preamplifiers, battery monitoring, DC gain stages, and transducer interfaces. Its quad configuration and low power consumption make it suitable for industrial control, consumer electronics, and portable battery-operated equipment.

Is the LM324AN/NOPB RoHS compliant and what does the /NOPB suffix mean?

Yes, the LM324AN/NOPB is RoHS compliant. The /NOPB suffix indicates 'No Lead (Pb)' — confirming the device uses a lead-free finish in line with RoHS environmental regulations. The Pb-free code is confirmed as 'Yes' in Texas Instruments' product documentation.

What package type does the LM324AN/NOPB use and are pin-compatible alternatives available?

The LM324AN/NOPB comes in a Dual-In-Line (DIP) through-hole package, making it easy to use on breadboards and through-hole PCBs. Pin-compatible alternatives include the LM324N and LM224N from Texas Instruments, as well as third-party equivalents from ON Semiconductor and STMicroelectronics that share the same pinout and functionality.
