The shutdown pin lets a GPIO or power-management IC put the amplifier into a low-current state when audio is idle. Thermal protection folds back output current if the die exceeds safe junction temperature — useful in compact enclosures with limited airflow. ## Temperature grade and environment Rated for -40°C to 85°C ambient, the LM4879ITPX/NOPB is suitable for outdoor telecom, industrial control panels, and automotive cabin audio where the environment stays above the under-hood range. The 8-µSMD package is not hermetically sealed; conformal coating is recommended if condensation or dust is present. ## Lifecycle and sourcing posture The LM4879ITPX/NOPB carries an Active lifecycle status and is ROHS3 compliant. This part is sourced and quoted to order through independent distribution; availability and current pricing are confirmed at quote time.","metaTitle":"TI LM4879ITPX/NOPB Boomer® Class AB Audio Amplifier, 1.1W","metaDescription":"TI LM4879ITPX/NOPB Boomer® Class AB audio amp, 1.1W mono into 8Ω, 2.2V–5.5V supply, -40°C to 85°C, 8-µSMD.
