20W+20W+20W AF Power Amplifier

Leave a Comment
Overview:

The STK400-030 is a 3-channel AF power amplifier IC supporting multichannel speakers. One package includes 20W×3ch for Lch, Rch and Cch. It is pin compatible with both 3-channel output devices (STK400-*00 series) and 2- channel output devices (STK401-*00 series). The output load impedance is 6/3Ω.

Features:

  • New series combining 3-channel output devices (STK400-*00 series) and 2-channel output devices (STK401-*00 series) with the same pin compatibility. 
  • Output load impedance is 6/3Ω. 
  • Pin assignment is grouped into individual blocks of inputs, outputs and supply lines, minimizing the adverse effects of pattern layout on operating characteristics.
  • Minimum number of external components required.
