TEST CIRCUIT ICC (Opr.)

CCP CALCULATION

CPD is to be calculated with the following formula

by using the measured value of ICC (Opr.) in the

test circuit opposite

CPD

=

ICC

fIN

(Opr.)

x VCC

In determining the typical value of CPD, a

relatively high frequency of 1MHz was applied to

fIN, in order to eliminate any error caused by the

quiescent supply current.
