STK404-070N-E

Overview

The STK404-070N-E is a hybrid IC for the audio power amplifier that mounts discrete components as the audio

power amplifier circuit in small space using the original Insulated Metal Substrate Technology IMST. The compact

package has been achieved by adopting the low thermal resistance substrate (our conventional model kind ratio).

Application

• Audio Power use

Features

• Pin-to-pin compatible outputs ranging from 60W to 180W

• Miniature package

• Output load impedance: RL = 6Ω recommended.

• Allowable load shorted time: 0.3 second

• Allows the use of predesigned applications for standby, mute, and the load short protection circuit.
