The ICCINT calculation provides an ICC estimate based on typical
conditions using a pattern of a 16–bit, loadable, enabled, up/down
counter in each LAB with no output load. Actual ICC should be verified
during operation because this measurement is sensitive to the actual
pattern in the device and the environmental operating conditions.
Figures 12 and 13 show the typical supply current versus frequency for
MAX 3000A devices.
