Product details

The Texas Instruments LM4879SD/NOPB is a Boomer® series Class AB audio amplifier delivering 1.1W into an 8Ω load from a single mono channel. That power level suits portable speakers, headphone drivers, and line-output stages in battery-powered gear where a small 8-WSON package keeps board area tight. The 2.2V to 5.5V supply range means it runs directly from a single Li-ion cell or a 3.3V/5V regulated rail without a boost converter — one less inductor on the BOM.

Industrial temperature grade and environment

The shutdown pin and thermal protection give a safety net if the amplifier is driven into clipping on a hot day — the die pulls back before damage, not after.

The NOPB suffix confirms lead-free (ROHS3) — no separate Pb-free qualification step needed.

Frequently asked questions

Is LM4879SD/NOPB lead-free?

Yes, the NOPB suffix indicates ROHS3 compliance — no lead, no RoHS-exempt substances.

What is the output power of LM4879SD/NOPB?

It delivers 1.1W into an 8Ω load from a single mono channel.
