Product details

What this amp is and where it fits

The LM4940TS/NOPB is a Class AB stereo audio amplifier from TI's Boomer® series, delivering 6W per channel into a 4Ω load. 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.

Frequently asked questions

What is the maximum output power per channel?

The LM4940TS/NOPB delivers 6W per channel into a 4Ω load, stereo (2-channel). That's the continuous sine-wave rating before clipping.
