STK400-490

Ordering number:ENN5247 Thick Film Hybrid IC STK400-490 3ch AF Power Amplifier (Split Power Supply) (25W + 50W + 25W, THD = 0.4%) Overview The STK400-490 is an audio power amplifier IC for multichannel speaker applications. It comprises two 25W channels (left and right) and a 50W channel (center) in a single package. It is fully pin compatible with the 3-channel output devices (STK400-×00 series) and 2-channel output devices (STK401-×00 series). In addition, it supports 6/3Ω output load impedance. Package Dimensions unit:mm 4086A [STK400-490] 78.0 70.0 Features Pin compatible with the 3-channel output devices (STK400-×00 series) and 2-channel output devices (STK401-×00 series) Output load impedance RL=6/3Ω supported Pin configuration grouped into individual blocks of inputs, outputs and supply lines to minimize the adverse effects of pattern layout on operating character- istics.
