6W/Ch STEREO CLASS-D AUDIO POWER AMPLIFIER
GENERAL DESCRIPTION
The TMPA402DS is a Single-ended (SE) 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 6W per channel. No external
heat-sink is necessary.
The gain of the amplifier can be changed by adding external
input resistance.
Thermal
protection
and
short-circuit
protection
are
integrated for safety purpose.
The internal depop circuitry eliminates pop noise at
power-up & shutdown operations.
PACKAGE
TSSOP20 available
FEATURES
6W/Ch Stereo Class-D Output
Power efficiency is up to 82%
Time delay for de-pop control
Thermal Protection
Output Pin Short-Circuit Protection (Short to
Other Outputs, Short to VCC, Short to Ground)
Low Quiescent Current (5mA Typical at 12V)
Low Current in Shutdown Mode (<1
μ
A Typical)
Separate VCC & PVCC
APPLICATIONS
LCD Monitors, TVs, DVD Players and Powered Speakers
