Supply decoupling should follow the 2.7V to 5.5V range — a 1 µF ceramic close to each supply ball and a 10 µF bulk cap per rail keeps the amplifier's PSRR from being degraded by trace inductance at the output switching edges. ## Output power and load matching Rated 1.575W continuous into an 8Ω load from a single channel — this is the mono speaker output at the supply voltage upper end. The stereo headphone output is a separate, lower-power path; the two outputs share the same Class AB output stage but the headphone path is current-limited to protect the earpiece.","metaTitle":"LM49100GR audio amplifier, 1.575W, 25-CSBGA","metaDescription":"LM49100GR Class AB audio amp, 1.575W mono into 8Ω, 2.7-5.5V supply, -40 to 85°C, 25-CSBGA 3x3mm.
