Overview
The STK433-290-E is a hybrid IC designed to be used in 80W ×3ch class AB audio power amplifiers.

Applications
•Audio power amplifiers.

Features
•Pin-to-pin compatible outputs ranging from 80W to 150W.
• Can be used to replace the STK433-000/-100 series (30W to 150W ×2ch) and STK433-200(A) series (30W to 60W ×3ch) due to its pin compatibility.
•Miniature package (64.0mm ×36.6mm ×9.0mm)
•Output load impedance: RL= 6Ωto 4Ωsupported
•Allowable load shorted time: 0.3 second
•Allows the use of predesigned applications for standby and mute circuits.
