Tai-1 Microelectronics www.taimec.com.tw / www.class-d.com.tw Preliminary TMPA402DS R ev.2.0 November 21, 2005 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 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 input resistance. Thermal protection and short-circuit protection are 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 (
