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 Figure 5). The average operating current can be obtained by the following equation:

ICC (opr.) = CPD x VCC x fIN + ICC/8.

1. Typical values are measured at TA = 25 °C. They are calculated as the difference from VOUT without injection current and

VOUT with injection current. IIN = total current injected into any other disabled channels, one at time.
