Overview
The STK433-090-E is a hybrid IC designed to be used in 80W ×80W (2-channel) class AB audio power amplifiers.

FEATUREs
•Pin-to-pin compatible outputs ranging from 80W to 150W.
•Can be used to replace the STK433-200, STK433-300 series (3-channel) due to its pin compatibility.
•Miniature package (67.0mm ×25.6mm ×9.0mm)
•Output load impedance: RL= 6Ω supported
•Allowable load shorted time: 0.3 second
•Allows the use of predesigned applications for standby and mute circuits.

APPLICATIONs
•Audio power amplifiers.
