15 W MONO CLASS D AUDIO POWER AMPLIFIER
General Description
The TMPA401DM is a bridged-tied (BTL) Class-D audio amplifier for driving speakers with high power efficiency. It can drive 4Ω, 6Ω, 8Ω or 16Ω speakers. The output power can be up to 15W. No external heat-sink is necessary. The gain of the amplifier is defined by input resistance. The internally fully differential input structure provides good common mode rejection and power supply rejection. Thermal protection and short-circuit protection are integrated for safety purpose. The internal de-pop circuitry eliminates pop noise at power-up & shutdown operations.
