Product details

The Texas Instruments LM4811MM/NOPB is a Boomer® series Class AB stereo headphone amplifier in a 10-VSSOP package. It delivers 105mW per channel into a 16Ω load.

Built-in features that simplify the BOM

Depop circuitry suppresses the turn-on / turn-off pop that otherwise needs external mute FETs or series capacitors. The shutdown pin lets a GPIO or power-management IC cut supply current to near zero when the audio path is idle. Thermal protection prevents die damage under a sustained fault. Volume control is integrated, so the design avoids a separate potentiometer or I²C volume chip.
