The TPA3113D2PWP is a 6W Stereo Class-D Audio Power Amplifier with SpeakerGuard? 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 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 TPA3113D2 can drive stereo speakers as low as 4R. The high efficiency 87% 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.
