STK433-040-E

Overview

The STK433-040-E is a hybrid IC designed to be used in 40W

× 2ch class AB audio power amplifiers.

Applications

• Audio power amplifiers.

Features

• Pin-to-pin compatible outputs ranging from 30W to 60W.

• Can be used to replace the STK433-100 series (80W to 150W/2ch) and STK433-200/-300 series (3-channel) due to its

pin compatibility.

• Miniature package (47.0mm × 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.
