The TPA313xD2 are efficient, stereo digital amplifier power stages for driving speakers with up to 2×42W/4Ω peak power. TPA3131/32D2 operates heatsink-free with cooling to PCB through the bottom side PowerPAD with sustained output power from 2 × 4 W / 8 Ω (TPA3131D2) to 2 × 25 W / 8 Ω (TPA3132D2).

The TPA313xD2 advanced oscillator/PLL circuit employs a multiple switching frequency option to avoid AM interferences; this is achieved together with an option of Master and Slave synchronization, making it possible to synchronize multiple devices.

The TPA313xD2 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.

For feature compatible devices see: PowerPAD up device 2 × 50-W TPA3116D2, PowerPAD down 2 × 15-W TPA3130D2 and 2 × 30-W TPA3118D2.
