That 1W figure is the headline for driving a small mono speaker in a portable device — think Bluetooth speaker, handheld radio, or a single-channel alarm. The same amplifier also puts 110mW into 32Ω headphones, so the same IC can serve both the speaker and the headphone jack in a single-ended mono design. The supply range is 2.7V to 5.5V, which means it runs cleanly off a single Li-ion cell (3.0–4.2V) or a regulated 3.3V/5V rail. At 2.7V the output power drops, but the amplifier still operates — useful for a device that keeps playing audio as the battery depletes. ## Depop, mute, shutdown — the features that matter in a portable audio chain The LM4875 includes depop circuitry that suppresses the audible pop and click when the amplifier powers up or exits shutdown. Without depop, the DC offset transient at turn-on couples through the speaker and sounds like a thump — this IC handles that internally. The shutdown pin lets a GPIO from the host MCU cut the amplifier's quiescent current to near-zero when audio is not playing, extending battery life in a duty-cycled product. Thermal protection is built in: if the die temperature exceeds the limit, the output stage folds back to prevent damage. This is standard for Class AB parts driving low-impedance loads, but worth noting if the amplifier is mounted in a tight enclosure without airflow. ## 8-VSSOP footprint — board integration for space-constrained designs The LM4875MM/NOPB is offered in an 8-lead VSSOP package (3.00mm × 3.00mm body, 0.65mm pitch). The supplier device package is 8-VSSOP, which is the same mechanical outline as 8-MSOP and 8-TSSOP in this width. The small footprint suits it for wearable audio, earbud charging cases, or any PCB where the audio amplifier must fit alongside the codec and battery management in a few square millimeters. ## Active lifecycle and industrial temperature range It is ROHS3 compliant, meaning no RoHS exemption issues for EU or global markets.","metaTitle":"Texas Instruments LM4875MM/NOPB Class AB Amp, 1W x 1 @ 8Ω","metaDescription":"Texas Instruments LM4875MM/NOPB Class AB audio amplifier, 1W into 8Ω mono, 110mW into 32Ω headphones.
