3 Description

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 heat-

sink 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.

The TPA31xxD2 devices are fully protected against

faults

with

short-circuit

protection

and

thermal

protection as well as overvoltage, undervoltage, and

DC protection. Faults are reported back to the

processor to prevent devices from being damaged

during overload conditions.
