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.

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.
