Product details

35 mW per channel into 32 Ω — what that means for portable audio

The Texas Instruments LM4910MM/NOPB is a Boomer® series Class AB stereo headphone amplifier delivering 35 mW per channel into a 32 Ω load. The depop circuitry suppresses the click and pop on power-up and shutdown that otherwise annoys the listener in a headphone application.

Thermal protection on-die prevents latch-up or damage if the output is shorted or the part is driven into a low-impedance load at high ambient.

Stereo output in a compact 8-VSSOP footprint

Surface-mount assembly with standard reflow profiles; the 8-VSSOP is a common footprint shared across many Boomer and competitor headphone amps, easing second-source qualification.

The NOPB suffix confirms lead-free / RoHS3 finish — no separate Pb-free conversion needed.

Frequently asked questions

What is the output power of LM4910MM?

The LM4910MM delivers 35 mW per channel into a 32 Ω load, stereo. That is the rated maximum output power for headphone drive — sufficient for most portable earbuds and headphones up to moderate listening levels.

Is LM4910MM RoHS compliant?

Yes, the LM4910MM/NOPB is ROHS3 compliant. The NOPB suffix indicates lead-free / RoHS-compliant plating.
