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

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