(1) Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings

conditions "is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.


Description

The TMPA401DM is a bridged-tied (BTL) Class-D audio amplifier for driving speakers with high power efficiency. It can drive 4, 6, 8 or 16 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.
