That output level is sufficient for consumer portable audio — earbuds and on-ear headphones typically need 10–30 mW for comfortable listening levels, so this part has headroom for dynamic peaks without clipping. The wide input tolerance means the amplifier stays in regulation as the battery discharges, avoiding the audible dropout that a fixed-rail LDO-based design would hit at 3.0 V. ## I²C volume control and depop — integration for space-constrained boards Volume is set via I²C, eliminating the need for a separate potentiometer or digital-to-analog converter for gain control. The depop circuit suppresses the turn-on/turn-off thump that otherwise couples into the headphones — a common complaint in Class AB designs without this feature. That footprint fits on a two-layer board if the fan-out vias are placed between the balls, but a four-layer stack-up with a dedicated ground plane under the amplifier simplifies routing and reduces crosstalk between the left and right channels. No pin-compatible second source is listed in the Boomer® family, so the BOM position is single-sourced to this TI order code.","metaTitle":"LM48822TL Texas Instruments Boomer® Class AB Audio Amp","metaDescription":"LM48822TL Texas Instruments Boomer® Class AB headphone amplifier, 40mW x 2 @ 32Ω, I²C volume control, 2.4-5.5V supply, -40 to 85°C, 16-DSBGA.
