* Output should be opened when measuring current consumption.

* Cpd is IC's inner equivalent capacity which is calculated from non-loaded operating current consumption referred to test

circuit. Averaged operating current consumption at non load is calculated as following formula: Idd(opr)=Cpd • Vdd • fin+Idd
