No last-time-buy notice is in effect. ## Thermal protection and shutdown Built-in thermal protection shuts down the output stage if the die temperature exceeds the safe limit, protecting the amplifier and the speaker load during a fault. The shutdown pin (active-low) allows the system controller to force the amplifier into a low-power state. Mount the 8-SOIC with adequate copper pour on the PCB pads for heat spreading — the package relies on the board copper for thermal dissipation, not an external heatsink.","metaTitle":"LM4861M/NOPB TI Boomer Class AB Audio Amp, 1.5W Mono 8SOIC","metaDescription":"Texas Instruments LM4861M/NOPB Class AB audio amplifier, 1.5W mono output into 8Ω, 2V-5.5V supply, -40°C to 85°C, 8-SOIC.
