SA7347
4-CH AUDIO POWER AMPLIFIER(8W X4)
DESCRIPTION
SA7347 is a four channel audio amplifier including two non
inverted amplifiers and two inverted amplifiers, so it can be
conveniently applied in Bridge-Tied Load (BTL) mode.
Built-in protection circuit based on multiple temperature
measurements inside SA7347 makes it possible for all supply
voltages and load conditions to export maximum power.
FEATURES
* Soft clip
* Standby and mute mode
* No on/off switching plops
* High supply voltage ripple rejection
* Thermally protected
* Outputs short circuit protected to ground, supply and across
the load
APPLICATIONS
* Television, PC speakers and mini stereo system, etc
