AC Electrical Characteristics
Capacitance (Note 3)
Note 3: TA = +25C, f = 1 MHz.
Note 4: CPD is defined as the value of the internal equivalent capacitance which is derived from dynamic operating current consumption (ICCD) at no output
loading and operating at 50% duty cycle. (See Figure 2) CPD is related to ICCD dynamic operating current by the expression:
ICCD = (CPD)(VCC)(fIN) + (ICCstatic).
