CAPACITIVE CHARACTERISTICS
1) CPD is defined as the value of the IC’s internal equivalent capacitance which is calculated from the operating current consumption without
load. (Refer to Test Circuit). Average operating current can be obtained by the following equation. ICC(opr) =CPD xVCC xfIN +ICC
TEST CIRCUIT
CL = 50pF or equivalent (includes jig and probe capacitance)
RT =ZOUT of pulse generator (typically 50)
