15-W MONO CLASS-D AUDIO POWER AMPLIFIER
GENERAL DESCRIPTION
FEATURES
The TMPA401DM is a bridged-tied (BTL) Class-D audio
amplifier for driving speakers with high power efficiency. It
can drive 4Ω, 6Ω, 8Ω or 16Ω speakers. The output power
can be up to 15W. No external heat-sink is necessary.
♦ 15-W Class-D Output
♦ Power efficiency is up to 82%
♦ Time delay for de-pop control
♦ Thermal Protection
The gain of the amplifier is defined by input resistance. The ^{♦ Output Pin Short-Circuit Protection (Short to}
internally fully differential input structure provides good
Other Outputs, Short to VCC, Short to Ground)
common mode rejection and power supply rejection.
♦ Differential / Single-Ended Input
Thermal protection and short-circuit protection are ^{♦ Low Supply Current (5mA Typical at 12V)}
integrated for safety purpose.
♦ Low Current in Shutdown Mode (<1µA Typical)
♦ Separate VCC & PVCC
The internal de-pop circuitry eliminates pop noise at
power-up & shutdown operations.
