DESCRIPTION
The TK15125M is a dual power supply Mute IC of the
Grand Earthing System that was developed as a low
frequency signal attenuator for audio products.
The mute function includes two channels which operate
simultaneously by one control key.
The optional time for the Attack/Release action can be set
up by an external timing control capacitor.
The TK15125M is available in a SOP-14 Surface Mount
Package.
