Product details

What this part is and where it fits

The LM4953SD/NOPB from Texas Instruments is a single-channel audio amplifier. 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.

Sourcing and lifecycle reality

The LM4953SD/NOPB carries an Active product status. That means no end-of-life notice is in effect, and the manufacturer continues to support it. For procurement, this part can be specified into production without an LTB clock ticking.

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.
