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 = 6 recommended. Allowable load shorted time: 0.3 second Allows the use of predesigned applications for standby, mute, and the load short protection circuit.
