MSP430FG479: SD16_A External Reference Voltage Range.

Part Number: MSP430FG479


I have a question for SD16_A external reference voltage range in MSP430FG479.

I can found out following table in datasheet.

Is the table meaning external reference voltage range?, If it is not, what is external reference voltage?

For other MSP430 Series, the ADC external reference voltage range is up to AVCC but I could not find the Similar table in datasheet of MSP430FG479.

Thank you.

  • Hi Wayne,
    this is the actual maximum external voltage, which can be applied to the SD16_A reference input. This is a result of the SD16_A architecture.

    You're correct. With our SAR ADCs in the MSP430 portfolio, one can apply AVcc voltage levels as external reference.

    Best regards
