ConnectCore 8M Mini: MCA ADC A/D conversion characteristics

Embedded Devices
1

I’m looking for the A/D conversion characteristics for the MCA ADC on the ConnectCore 8M Mini that I would typically find in a microcontroller datasheet. I want to make sure I am not exceeding any specifications. For the MCA ADC inputs, what are the:

  • Maximum input voltage
  • Maximum reference voltage
  • Analog input capacitance
  • Maximum permissible signal source impedance
  • Any characteristic changes when using the internal ADC reference voltage vs. providing an external voltage reference

Thanks,

Bryan

you should contact Digi Technical Support with the serial number of your board/SOM:
