Class D mono amplifier — 18 W into 16 Ω, industrial rated
The Maxim Integrated MAX9703ETJ+T is a Class D mono audio amplifier delivering 18 W continuous into a 16 Ω load from a single supply rail spanning 10 V to 25 V. The Class D switching topology keeps quiescent losses low, so the 32-TQFN (5x5) package with exposed pad handles the thermal load without forced air in most installations. On-chip short-circuit and thermal protection, plus a mute function and shutdown input, give the system designer a clean supervisory interface. The differential inputs reject ground noise picked up over long signal runs — useful in automotive infotainment or distributed audio where the amplifier sits remote from the source.
