Product details

Class AB mono output stage — 825 mW into 8 Ω

The LM4862M/NOPB is a Texas Instruments Boomer® Class AB audio amplifier delivering 825 mW continuous into an 8 Ω load from a single 5 V supply. That output level suits portable speakers, alarms, or voice prompts where a single speaker channel is enough and the PCB area stays under 5×6 mm.

Supply range and shutdown — battery-friendly

The shutdown pin pulls the quiescent current to near zero — useful for battery-powered devices that sleep between audio bursts. Thermal protection clamps the output if the die temperature exceeds the safe limit, which matters when the amplifier drives continuous tones into a low-impedance speaker inside a sealed enclosure.

8-SOIC package and industrial temperature grade

ROHS3 compliant — no exemption-laden materials; the NOPB suffix confirms lead-free assembly for RoHS-regulated markets.
