That means one chip handles both a small speaker and a headphone jack in a portable device — no second amplifier needed. ## Pop suppression and thermal shutdown built in The depop and mute features eliminate the turn-on thump that would otherwise hit the speaker, so the BOM can skip the external muting FET. Thermal protection shuts the amplifier down before the die overheats — useful when the 8-VSSOP package is packed into a tight enclosure with little airflow. The shutdown pin lets a microcontroller pull the amplifier into a low-current state between audio bursts, saving battery in a portable design. Volume control is integrated, reducing external pot count. ## Supply and temperature range for portable gear The 2.7V to 5.5V supply covers single-cell Li-ion (3.0-4.2V) and regulated 3.3V or 5V rails. Supplied in an 8-VSSOP package (the 8-TSSOP / 8-MSOP footprint family), 3.00 mm body width. The surface-mount package is easy to hand-solder with a fine-tip iron — no hot-air station required — so a field-service tech can swap it on site if the board has accessible pads.","metaTitle":"LM4865MM/NOPB Texas Instruments Class AB Audio Amp, 1W Mono","metaDescription":"Texas Instruments LM4865MM/NOPB Class AB audio amplifier, 1W mono output into 8Ω, 2.7-5.5V supply, 8-VSSOP package.
