Product details

It is designed to drive a speaker load from a low-voltage supply, typical in portable audio, headphone amps, or small-signal line drivers. The part is listed as active in lifecycle, so it remains a current-production choice for new BOMs and replacement builds alike.

Package and handling at the bench

This part ships in Bulk — loose tubes or antistatic bags, not tape-and-reel. For a rework tech that means no carrier tape to manage; just lift the part from the tube with tweezers.

That means no end-of-life notice is in effect, and the manufacturer continues to support it.

Frequently asked questions

What is the LM4953SD/NOPB?

The LM4953SD/NOPB is a single-channel audio amplifier from Texas Instruments, used for driving speakers or headphones in portable and low-voltage audio applications.

What is the difference between LM4953SD and LM4953SD/NOPB?

The /NOPB suffix indicates a lead-free (no-lead) finish. The LM4953SD without the suffix may use a tin-lead finish. Functionally they are the same amplifier, but the /NOPB variant meets RoHS requirements for lead-free assembly.

What is the pinout of LM4953SD/NOPB?

The pinout follows the standard small-outline footprint for this audio amplifier family. Pin 1 is marked by a dot on the package top. Refer to the manufacturer datasheet for the exact pin assignments.
