It delivers 95 mW per channel into a 16 Ω load — enough drive for standard earbuds and small headphones in portable audio gear. The supply range of 1.4 V to 3.6 V lets it run directly from a single lithium-ion cell or two alkaline batteries, which makes it a natural fit for battery-powered consumer audio, handheld instruments, and portable communication devices. The industrial temperature grade (-40°C to 85°C) extends its reach into outdoor handhelds, automotive cabin audio, and factory-floor alert systems. ## Key features that matter for the BOM The LM4917MTX/NOPB includes depop circuitry to suppress turn-on/turn-off clicks — a practical concern for headphone outputs where audible pops annoy the user. Short-circuit and thermal protection add fault tolerance on the output, reducing the risk of field failures from a shorted headphone jack. A shutdown pin lets the system cut supply current when the headphones are unplugged, extending battery life in portable designs. The 14-TSSOP body (0.173\" wide, 4.40 mm) is a compact surface-mount footprint that fits tight PCB layouts in handheld and wearable products. The stereo output is ground-referenced, which eliminates the need for large DC-blocking output capacitors — a real board-area and BOM-cost saver compared to older single-supply headphone amps. ## Lifecycle and sourcing reality The LM4917MTX/NOPB is listed as Active in production. No NRND or EOL notice is on record. Sourcing is through independent distribution — availability and current pricing are confirmed at quote time against an RFQ.","metaTitle":"LM4917MTX/NOPB Class AB Headphone Amp, 95mW x 2 @ 16Ω","metaDescription":"TI LM4917MTX/NOPB Boomer® Class AB stereo headphone amplifier. 95mW per channel into 16Ω, 1.4V–3.6V supply, industrial temp.
