3 Description

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

Class-D audiopower amplier for drivingbridged-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

circuitryincludes an adjustable power limiter and a

DC detection circuit. The adjustable power limiter

allowsthe user to set a "virtual"voltage rail lower

than the chip supply to limitthe amount of current

through thespeaker. The DC detectcircuitmeasures

the frequency and amplitude of the PWM signal and

shuts othe outputstage ifthe inputcapacitors are

damaged orshorts existon theinputs.

The TPA3110D2 can drive stereo speakers as low as

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

eliminatestheneed foran external heatsink when

playing music.

The outputs arealso fullyprotected againstshorts to

GND, VCC, andoutput-to-output. Theshort-circuit

protection and thermalprotection includes anauto-

recovery feature.
