TPA3131D2EVM for 7W Class-D Speaker Amplifier


Order now


The TPA3131D2EVM is a stereo analog input, Class-D speaker amplifier IC for driving speakers with output power of 2x7W into 8Ω. TPA3131D2 operates heat sink-free with cooling to the PCB through the PowerPAD™ package. The TPA3131 has an advanced oscillator/PLL circuit which employs a multiple switching frequency option to avoid AM interference. A Master/Slave option makes it possible to synchronize multiple devices. The TPA3131D2 is fully protected against faults with short-circuit protection and thermal protection as well as over-voltage, under-voltage and DC protection
