Thick-Film Hybrid IC
1ch class-AB Audio Power IC
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).
Audio Power use
Pin-to-pin compatible outputs ranging from 60W to 180W
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.
