Depop circuitry suppresses the click and pop on power-up and shutdown, which matters for customer-facing audio in a car cabin. ## Package and mounting The 14-HTSSOP package (4.40 mm width, exposed pad) requires a thermal land on the PCB — the exposed pad must be soldered to a copper plane for the 1.6W dissipation. Surface-mount assembly; the tape-and-reel option suits automated pick-and-place. The 0.173-inch body pitch is standard for TSSOP, so no special stencil or reflow profile needed beyond the usual for that family.","metaTitle":"LM48100QMHX/NOPB Class AB Audio Amp, 1.6W Mono, 14-HTSSOP","metaDescription":"TI LM48100QMHX/NOPB Class AB audio amplifier, 1.6W mono into 8Ω, I²C volume control, AEC-Q100, -40 to 105°C.
