Thick-Film Hybrid IC
3-channel class AB audio power IC,
The STK433-240A-E is a hybrid IC designed to be used in 40W × 3ch class AB audio power amplifiers.
• Audio power amplifiers.
• Pin-to-pin compatible outputs ranging from 30W to 60W.
• Can be used to replace the STK433-000/-100 series (30W to 150W/2ch) and STK433-300 series (80W to 150W/3ch) due
to its pin compatibility.
• Miniature package (67.0mm × 25.6mm × 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.
