STK433-890-E
Thick-Film Hybrid IC
4-channel class AB audio power IC,
80W×4ch
Overview
The STK433-890-E is 80W×4 channels class-AB audio frequency power amplifier hybrid IC.
Applications
• Audio power amplifiers.
Features
• Pin-to-pin compatible outputs ranging from 60W to 80W
• Can be used to replace the STK433-000/-100 series (30W to 150W/2ch/class-AB), STK415-100Series (80W to
150W/2ch/class H) due to its pin compatibility of ch1/ch2.
2ch class AB (30W to 60W, THD=10%) : STK433-000 series
2ch class AB (80W to 150W, THD=10%) : STK433-100 series
2ch class H (80W to 150W, THD=10%) : STK415-100 series
• Compact package (64.0mm×31.1mm×9.0mm, 78.0mm×44.1mm×9.0mm)
• Output load impedance RL=6Ω, 8Ω supported.
• Allowable load shorted time: 0.3s
• Allows the use of predesigned applications for standby and mute circuits
