STK400-030

Ordering number: EN 5703 Thick Film Hybrid IC STK400-030 AF Power Amplifier (Split Power Supply) (20W+20W+20W, THD = 0.4%) 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 2channel output devices (STK401-*00 series). The output load impedance is 6/3Ω. Package Dimensions unit: mm 4086A [STK400-030] 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.
