Class D mono amplifier for single-speaker audio lines
The MAX9713ETJ+ from Maxim Integrated is a Class D mono audio amplifier delivering 8W into a 16Ω load from a single channel. It operates from a 10V to 25V supply rail, suiting it for distributed audio systems, powered speakers, and automotive aftermarket head units where a single speaker channel is needed. The 32-TQFN (5x5) exposed-pad package aids thermal dissipation in compact enclosures. Integrated features include differential inputs for noise rejection, a mute function, depop circuitry to suppress turn-on clicks, and short-circuit/thermal protection. The shutdown pin allows the amplifier to be disabled when idle, saving system power. Rated for -40°C to 85°C ambient, this part fits industrial-temperature environments such as outdoor paging systems, public-address amplifiers, and equipment racks without forced cooling.
