The part includes depop circuitry to suppress turn-on thumps, differential inputs for noise rejection in mixed-signal layouts, and a shutdown mode for battery conservation. ## Package and mounting Housed in an 8-WFDFN with exposed pad (supplier package 8-WSON, 2.5x2.5 mm), this is a small outline no-lead package meant for surface-mount assembly. A via stitch under the pad to the ground plane is standard practice. The 2 V minimum supply is worth noting for deeply-discharged Li-ion scenarios: the amplifier still produces usable audio down to that rail, though output swing is reduced. At 5.5 V the full 350 mW into 16 Ω is available.","metaTitle":"TI LM4819LDX/NOPB Class AB Audio Amp, 350mW mono","metaDescription":"Texas Instruments LM4819LDX/NOPB Boomer® Class AB audio amplifier, 350mW into 16Ω mono, 2V-5.5V supply, industrial temp.
