Description

The TMPA420DS is a Bridge-Tied-Load (BTL) output Class-D audio power amplifier for driving speakers with high power efficiency. It is able to drive 4, 6, 8 or 16 speakers. The output power can be up to 15W per channel. No external heat-sink is necessary.

The gain of the amplifier is defined by either gain0/gain1 gain control or by input resistance. Thermal protection and
short-circuit protection are integrated for safety purpose. The internal de-pop circuitry eliminates pop noise at power-up & shutdown operations.
