DESCRIPTION

The TPA3113D2 is a 6-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. SpeakerGuard™ 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.
