No.7777-5/9

Relation of MUTE and Power (VCC*)

* Connect VCC1 and VCC2 externally (to reduce the effects of voltage drop in the internal metal wiring).

* MUTE operates independently for each CH.

Relation of Each Channel and VREF

* CH1 through CH4 operate for external VREF.

CH5 operates for internal VREF (1.65V (TYP) : fixed).
