STK433-290-E
Thick-Film Hybrid IC
3-channel class AB audio power IC,
80W+80W+80W
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 = 6Ω to 4Ω supported
• Allowable load shorted time: 0.3 second
• Allows the use of predesigned applications for standby and mute circuits.
