TPA3116D2 Datasheet – Filter-Free Class-D Stereo Amplifier

Part number : TPA3116D2, TPA3118D2, TPA3130D2

Functions : Filter-Free Class-D Stereo Amplifier

Package information :32-Pin HTSSOP Type

Manufacturer : Texas Instruments


TPA3116D2 Stereo Amplifier


The TPA31xxD2 series are stereo efficient, digital amplifier power stage for driving speakers up to 100 W / 2 Ω 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 / 8 Ω without heat sink on a dual layer PCB. If even higher power is needed the TPA3116D2 does 2 × 50 W / 4 Ω with a small heatsink attached to its top side PowerPAD. All three devices share the same footprint enabling a single PCB to be used across different power levels. 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 master or slave option, making it possible to synchronize multiple devices.
