ÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎ 2. 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 / 8 (per bit). CPD is used to determine the no−load
dynamic power consumption; PD = CPD VCC2 fin + ICC VCC.
