TPA3116D2DAD

TPA3116D2DAD is a TPA31xxD2 series stereo efficient, digital amplifier power stage for driving speakers up to 100W / 2ohm in mono. The high efficiency of the TPA3130D2 allows it to do 2 × 15 W without external heat sink on a single layer PCB. The TPA3118D2 can even run 2 × 30 =W / 8ohm without heat sink on a dual layer PCB. If even higher power is needed the TPA3116D2 does 2 × 50W / 4ohm with a small heatsink attached to its top side PowerPAD. The TPA31xxD2 advanced oscillator/PLL circuit employs a multiple switching frequency option to avoid AM interferences; this is achieved together with an option of either host or server option, making it possible to synchronize multiple devices. It is fully protected against faults with short-circuit protection and thermal protection as well as overvoltage, undervoltage, and DC protection. Applications include mini-micro component, speaker bar, docks, after-market automotive, CRTTV, consumer audio applications.
