It's built for surface-mount assembly in the DDPAK/TO-263-9 package — a 9-lead tabbed package that sinks heat through the PCB copper. The 10V to 16V supply range keeps it on a standard 12V or 15V audio rail. Industrial temperature rating (-40°C to 85°C) means it can sit in outdoor paging systems, automotive aftermarket head units, or factory-floor audio zones without derating. ## Key ratings and what they mean for your BOM 6W x 2 into 4Ω is the continuous sine-wave output per channel before clipping. Protection features include short-circuit and thermal shutdown. The Depop feature suppresses the power-on thump. ## Lifecycle and sourcing reality TI lists the LM4940TS/NOPB as Active and ROHS3 compliant. Sourced and quoted to order against an RFQ through independent distribution.","metaTitle":"LM4940TS/NOPB Class AB Stereo Amp, 6W x 2 @ 4Ω, TO-263-9","metaDescription":"LM4940TS/NOPB is an active Class AB stereo audio amplifier from TI's Boomer® series.
