CPD is defined as the value of the internal equivalent capacitance which is calculated from the operating current consumption without load. Average operating current can be obtained by the equation: ICC (Opr.) = CPD • VCC • fIN + ICC Symbol Parameter VCC (V) Conditions TA = 25°C TA = –40°C to +85°C Units Min. Typ. Max. Min. Max.
