Texas Instruments TPA3116D2DAD
The TPA31xxD2 series are stereo efficient, digital amplifier power stage for drivingspeakers up to 100 W / 2 Ω in mono. The high efficiency of the TPA3130D2 allows it to do 2 × 15 Wwithout external heat sink on a single layer PCB. The TPA3118D2 can even run 2 × 30 W / 8 Ω withoutheat sink on a dual layer PCB. If even higher power is needed the TPA3116D2 does 2 × 50 W / 4 Ωwith a small heat-sink attached to its top side PowerPAD. All three devices share the samefootprint enabling a single PCB to be used across different power levels.
The TPA31xxD2 advanced oscillator/PLL circuit employs a multiple switching frequencyoption to avoid AM interferences; this is achieved together with an option of either master orslave option, making it possible to synchronize multiple devices.
The TPA31xxD2 devices are fully protected against faults with short-circuit protectionand thermal protection as well as overvoltage, undervoltage, and DC protection. Faults are reportedback to the processor to prevent devices from being damaged during overload conditions.
