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, 6Ω, 8Ω or 16Ω 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 (<1µA Typical)
♦Separate VCC & PVCC
APPLICATIONS
LCD Monitors, TVs, DVD Players and Powered Speakers
