Active production — sourcing and compliance posture
The LM48512TL/NOPB: The part carries ROHS3 compliance, covering the full RoHS exemption set for global shipping into regulated markets.
1.8W mono Class D — efficiency and load fit
Rated 1.8 W into an 8 Ω load from a single channel — this is the maximum continuous output power before clipping, making it suitable for driving a single speaker in portable speakers, soundbars, or IoT voice-alert endpoints. Class D topology means the output stage switches at high frequency, keeping quiescent losses low and thermal rise manageable in the 16-DSBGA package without a heatsink — the efficiency advantage over a linear Class AB is what makes this part viable for battery-powered gear.
16-DSBGA footprint and board integration
Housed in a 16-bump DSBGA measuring 2.5 x 2.12 mm, the package suits space-constrained layouts where board real estate is at a premium — the 0.5 mm pitch requires a controlled solder-paste stencil and reflow profile, typical for wafer-level chip-scale packages. Mounting is surface-mount only; the DSBGA lands directly on the PCB without a molded body, so the board's solder-mask-defined pads set the standoff height.
Depop and shutdown — pop-free power sequencing
The depop feature suppresses the audible pop during power-up and power-down — this matters for battery-operated devices where the amplifier is frequently enabled and disabled to conserve charge, because a click on every wake cycle degrades the user experience. A dedicated shutdown pin lets the system pull the amplifier into a low-power state when no audio is needed, reducing idle draw to microamp levels.
