pF

7. 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. CPD is used to determine the no--load dynamic

power consumption: PD = CPD ¯ VCC2 ¯ fin + ICC ¯ VCC.
