TPA3131D2EVM: 4W x 2 @ 8Ω, 4.5 ~ 26V in

This evaluation module allows users to evaluate TI's TPA3131D2 audio amplifier. This user's guide contains an operations description, schematic, printed-circuit board (PCB) layout, and the bill of materials (BOM). The TPA3131D2EVM (EVM) customer evaluation module demonstrates the TPA3131D2 integrated circuit (IC) from Texas Instruments.

The TPA3131/32D2 are efficient, stereo digital amplifier power stages for driving speakers with up to 2x42W/4Ω peak power. TPA3131/32D2 operates heatsink-free with cooling to PCB through the bottom side PowerPAD™ with sustained output power from 2x4W/8Ω (TPA3131D2) to 2x25W/8Ω (TPA3132D2).

The TPA3131/32D2 advanced oscillator/PLL circuit employs a multiple switching frequency option to avoid AM interferences; this is achieved together with an option of Master/Slave option, making it possible to synchronize multiple devices.

The TPA3131/32D2 are fully protected against faults with short-circuit protection and thermal protection as well as over-voltage, under-voltage and DC protection. Faults are reported back to the processor to prevent devices from being damaged during overload conditions.
