Description
The TPA3110D2 is a 15-W (per channel) efficient, Class-D audio
power amplifier for driving bridged-tied stereo speakers. Advanced
EMI Suppression Technology enables the use of inexpensive ferrite
bead filters at the outputs while meeting EMC requirements.
SpeakerGuardTM speaker protection circuitry 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.
