15-W MONO CLASS-D AUDIO POWER AMPLIFIER
GENERAL DESCRIPTION
The TMPA401DM is a bridged-tied (BTL) Class-D audio
amplifier for driving speakers with high power efficiency. It
can drive 4
Ω
, 6
Ω
, 8
Ω
or 16
Ω
speakers. The output power
can be up to 15W. No external heat-sink is necessary.
The gain of the amplifier is defined by input resistance. The
internally fully differential input structure provides good
common mode rejection and power supply rejection.
Thermal
protection
and
short-circuit
protection
are
integrated for safety purpose.
The internal de-pop circuitry eliminates pop noise at
power-up & shutdown operations.
APPLICATIONS
LCD Monitors, TVs, DVD Players and Powered Speakers
FEATURES
15-W 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)
Differential / Single-Ended Input
Low Supply Current (5mA Typical at 12V)
Low Current in Shutdown Mode (<1
μ
A Typical)
Separate VCC & PVCC
PACKAGE
TSSOP20 available
