TPA3113D2

illustrate

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

The TPA3113D2 can drive as few as 4 stereo speakers 。
