AD5689 Maximum Voltage Reference Load

PawelSemi on Feb 21, 2017

It is possible to uses an internal voltage reference as exhobited in AD5689R also for another ICs within one project.

How much current it can delivery. I just want two uses two DACs, one with build in Ref Voltage (AD5689R) and one without internal Vref (AD5689).

Hi,

Yes, you may use the internal reference voltage of AD5689R as an external reference voltage for AD5689.

AD5689R can drive up to 10mA load and the AD5689's reference current is only 90uA (using gain =1).
hope that answers your question!

Cheers,

Ivan
