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.
