ADS8028: The limitation of internal reference

Hirotaka Matsumoto

Part Number: ADS8028

Hi all

Would you mind if we ask ADS8028?

Our customer would like to use internal reference for external reference circuit.
So, how much is the limitation of internal reference?
Is 20mA correct value?

Kind regards,

Hello,

Apologies for the late response

The internal reference is capable of sourcing up to 2 mA of current.

If it is being used in the circuit for more than the ADS8028, then a buffer at the output is needed to drive the signal.

Regards,

Cynthia
