6W/Ch STEREO CLASS-D AUDIO POWER AMPLIFIER
GENERAL DESCRIPTION
FEATURES
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 4Ω, 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
♦ 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)
input resistance.
♦ Low Quiescent Current (5mA Typical at 12V)
Thermal protection and short-circuit protection are ^{♦ Low Current in Shutdown Mode (<1µA Typical)}
integrated for safety purpose.
♦ Separate VCC & PVCC
The internal depop circuitry eliminates pop noise at _APPLICATIONS
power-up & shutdown operations.
LCD Monitors, TVs, DVD Players and Powered Speakers
