Description

 

The TMPA421DS is a 2.1 Channel Class-D output audio power amplifier for driving speakers with high power efficiency. The bass output is designed as BTL (Bridge-Tied-Load) for high output power. The right& left channels are designed as SE (Single-Ended). The outputs are able to drive 4, 6, 8 or 16 speakers. The output power can be up to 15W for bass and 6W for either Right or Left 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.
