It operates from a 2 V to 5.5 V supply, making it a fit for battery-powered portable audio — phones, tablets, portable media players, and handheld instrumentation where a single Li-ion cell or two alkaline cells provide the rail. The 8-VSSOP package keeps the board footprint small, and the -40°C to 85°C temperature range covers consumer and industrial ambient environments without derating. ## Built-in protection and shutdown The LM4809MM/NOPB includes depop circuitry to suppress turn-on/turn-off clicks, a shutdown pin for power saving, and thermal protection. The depop feature is worth noting — it saves an external mute circuit and avoids the pop that otherwise hits the headphones when the amplifier powers up. Shutdown drops quiescent current to microamps, extending battery standby time. ## Lifecycle and sourcing Texas Instruments lists the LM4809MM/NOPB as Active and ROHS3 compliant. For volume production, this part is quoted against an RFQ through independent distribution — availability and current pricing confirmed at quote time.","metaTitle":"LM4809MM/NOPB TI Boomer Class AB Stereo Headphone Amp, 105mW","metaDescription":"Texas Instruments LM4809MM/NOPB Boomer Class AB stereo headphone amplifier, 105mW per channel into 16Ω, 2V-5.5V supply, 8-VSSOP.
