GENERAL 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 operati***.
APPLICATI***
LCD Monitors, TVs, DVD Players and Powered Speakers
