Short-circuit and thermal protection are built in, so if the output gets shorted to ground or the amp runs hot, it shuts itself down rather than letting the magic smoke out. That's the kind of thing you appreciate when you're swapping a dead amp on site and the replacement has to survive whatever killed the original. ## Lifecycle and sourcing reality This part is listed as Active and ROHS3 compliant — no end-of-life notice, no last-time-buy pressure. It's a current production item from TI, so you can spec it into a new BOM without worrying about a sudden discontinuation. For procurement, we source it to order against an RFQ.","metaTitle":"LM4805LQ/NOPB Boomer® Class AB Audio Amp, 1.2W Mono, 28-WQFN","metaDescription":"LM4805LQ/NOPB is a 1.2W mono Class AB audio amplifier from TI's Boomer® series.
