The TPA3118D2DAP is a 30W Stereo (BTL) Class-D Audio Amplifier with SpeakerGuard? for driving speakers up to 100W/2R in mono. The high efficiency allows it to do 2 x 15W without external heat sink on a single layer PCB. The TPA3118D2 can even run 2 x 30W/8R without heat sink on a dual layer PCB. The TPA3118D2 advanced oscillator/PLL circuit employs a multiple switching frequency option to avoid AM interferences, this is achieved together with an option of either master or slave option, making it possible to synchronize multiple devices. The TPA3118D2 device is fully protected against faults with short-circuit protection and thermal protection as well as overvoltage, under-voltage and DC protection. Faults are reported back to the processor to prevent devices from being damaged during overload conditions.
