Analog-to-Digital Converter (ADC)

Technical Data

MC68HC908GR8 — Rev 4.0

Analog-to-Digital Converter (ADC)

MOTOROLA

5.7.1 ADC Analog Power Pin (VDDAD)/ADC Voltage Reference High Pin (VREFH)

The ADC analog portion uses VDDAD as its power pin. Connect the

VDDAD pin to the same voltage potential as VDD. External filtering may be

necessary to ensure clean VDDAD for good results.

NOTE:

For maximum noise immunity, route VDDAD carefully and place bypass

capacitors as close as possible to the package.

5.7.2 ADC Analog Ground Pin (VSSAD)/ADC Voltage Reference Low Pin (VREFL)

The ADC analog portion uses VSSAD as its ground pin. Connect the

VSSAD pin to the same voltage potential as VSS.

NOTE:

Route VSSAD cleanly to avoid any offset errors.

5.7.3 ADC Voltage In (VADIN)

VADIN is the input voltage signal from one of the six ADC channels to the

ADC module.
