Capacitance (note 1)
1) CPD isdefined as the value of the IC’sinternal equivalent capacitance which is calculated fromthe operating current consumption without load. (Referto
Test Circuit).Average operting current can be obtained by the following equation. ICC(opr) = CPD VCC fIN + ICC/n(per circuit)
