It comes in an 8-SOIC surface-mount package and operates over the industrial temperature range of -40°C to 85°C. Typical applications include portable audio devices, headphone drivers, and line-output stages in battery-powered or single-rail systems where a clean, low-distortion audio path is needed without a split supply. ## Shutdown and thermal protection — what they save you The shutdown pin lets a system controller mute the amplifier and cut quiescent current to near zero, useful for power-sensitive designs. The thermal protection circuit folds back output drive if the die temperature exceeds the safe limit, which means you can omit an external thermal fuse or supervisory circuit in many designs. Both features are integrated, not requiring external passives. ## Lifecycle and sourcing posture The LM4881M/NOPB is listed as Active with ROHS3 compliance. No end-of-life notice is on record, so it remains a safe choice for new production builds and ongoing BOM lines. It is sourced through independent distribution and quoted to order against an RFQ; availability and current pricing are confirmed at quote time.","metaTitle":"LM4881M/NOPB Class AB Stereo Headphone Amp, 300mW, 8-SOIC","metaDescription":"TI LM4881M/NOPB Class AB stereo headphone amplifier, 300mW x 2 into 8Ω. 2.7-5.5V supply, shutdown & thermal protection.
