15W/Ch STEREO CLASS-D AUDIO POWER AMPLIFIER
GENERAL 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
Ω
, 6
Ω
, 8
Ω
or 16
Ω
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.
APPLICATIONS
LCD Monitors, TVs, DVD Players and Powered Speakers
PACKAGE
QFN48 available
REFERENCE CIRCUIT
