TPA3113D2PWPR

Product Summary

The TPA3113D2PWPR 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 of the TPA3113D2PWPR 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 applications of the TPA3113D2PWPR include Televisions, Consumer Audio Equipment and Monitors.
