Note 1:

Does not include current consumption due to external loading on pins. Valid for a maximum voltage of 16.8 volts

for the referenced current specification.

2:

Sample mode current is specified during an A/D inactive cycle. Sample mode average current can be calculated using

sample rate.

3:

During LED illumination, currents may peak at 10 mA but average individual LED current is typically 5 mA (using

low-current, high-brightness devices).

4:

Measured at 25°C.
