3 Description
The TPA3112D1 is a 25-W efficient, Class-D audio
power amplifier for driving a bridge tied speaker.
Advanced EMI Suppression Technology enables the
use of inexpensive ferrite bead filters at the outputs
while meeting EMC requirements. SpeakerGuard
speaker protection system includes an adjustable
power limiter and a DC detection circuit. The
adjustable power limiter allows the user to set a
virtual voltage rail lower than the chip supply to limit
the amount of current through the speaker. The DC
detect circuit measures the frequency and amplitude
of the PWM signal and shuts off the output stage if
the input capacitors are damaged or shorts exist on
the inputs.
The TPA3112D1 can drive a mono speaker as low as
4Ω. The high efficiency of the TPA3112D1, > 90,
eliminates the need for an external heat sink when
playing music.
The outputs are fully protected against shorts to
GND, VCC, and output-to-output. The short-circuit
protection and thermal protection includes an autorecovery
feature.
