TPA3113D2

illustrate

The TPA3113D2 is a 6-watt (per channel) high-efficiency, Class D drivebridge stereo speaker audio power amplifier. Advanced electromagnetic interference suppression technology enables the use of inexpensive ferrite bead filters while meeting EMC requirements. SpeakerGuard™ speaker protection circuitry includes an adjustable power limiter and DC detection circuitry. The adjustable power limiter allows the user to set a "virtual" voltage rail than the chip supply limit with a low current value through the speaker. The DC detection circuit measures the frequency and amplitude of the PWM signal and shuts off the output stage if the input capacitor is damaged or the input on the shorts is present.

The TPA3113D2 can drive as many as 4 stereo speakers 。
