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.
