3 Description

The TPA3110D2 is a 15-W (per channel) ecient,

Class-D audio power amplier for driving bridged-tied

stereo speakers. Advanced EMI Suppression

Technology enables the use of inexpensive ferrite

bead lters 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 o the output stage if the input capacitors are

damaged or shorts exist on the inputs.

The TPA3110D2 can drive stereo speakers as low as

4 . The high eciency of the TPA3110D2, 90%,Ω

eliminates the need for an external heat sink when

playing music.

The outputs are also fully protected against shorts to

GND, VCC, and output-to-output. The short-circuit

protection and thermal protection includes an auto-

recovery feature.
