TPA3132D2EVM for 25W Class-D Speaker Amplifier


Order now


The TPA3132D2EVM is a stereo analog input, Class-D speaker amplifier IC for driving speakers with output power of 2x25W into 8Ω. TPA3132D2 operates heat sink-free with cooling to the PCB through the PowerPAD™ package. The TPA3132 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 TPA3132D2 is fully protected against faults with short-circuit protection and thermal protection as well as over-voltage, under-voltage and DC protection.

  • 25W output into a 8 Ohm load at 19V and 10% THD+N
  • Low shutdown current 32uA
  • Wide voltage range 4.5V – 26V
  • Multiple switching frequencies
  • Stereo and Mono modes
