... KA9259D(KA9259HD) Application Information 1. Mute Function Pin #7 Mute circuit High Mute-off Low Mute-on Open Mute-on • When the mute (pin 7) is high level, the bias circuit of BTL driver is activated. On the other hand, when the mute (pin7) is open or low level, the bias circuit of BTL driver is disabled. So that the 4-channels BTL driver output circuit will be muted. ...
