TDA8954TH 420W x 2 High Power Amplifier Board

$57.44
SKU 685280

Do you need huge stereo audio power to drive concert speakers? Then order the TDA8954TH 420W Stereo Amplifier Board from PMD Way. Based on the NXP TDA8954TH class-D amplifier IC in bridge-tied load, this monolith can pump 420W into an 8 Ohm load per channel. 

Furthermore the TDA8954TH combines the benefits of Class D efficiency (~93 % into a 4 Ohm load) with audiophile sound quality comparable to that associated with Class AB amplification.

Please note that you'll need to power this with a toroidal transformer such as a 25+25V 300VA unit. Do not use speakers rated less than 200W, otherwise they will just go BANG!

The board is fully assembled, and uses high-quality components such as Nichicon capacitors for longevity, cooling fans for the heatsinks - the works. The massive heatsinks are pre-fitted to the board. 

Specifications:

  • Low noise
  • Smooth pop noise–free start-up and switch off
  • Fixed frequency internal or external clock
  • input impedance 1k Ohm
  • Output power 420W into 4 Ohms
  • High efficiency (~93 %)
  • Zero dead time switching
  • Low quiescent current

  • Thermal FoldBack (TFB) with disable functionality
  • Fixed gain of 36 dB 
  • Fully short–circuit proof across load
  • board measures 142 x 106 x 25mm
  • requires 25+25V 300VA toroidal transformer
