ADS825: External reference

Gopika Raj V S
Intellectual 360 points

Part Number: ADS825

I need to give external reference to the ADC  ADS825 using a voltage reference IC. I am taking Vs as +5V and I need to adjust the REFT and REFB externally. Please provide the reference scheme for the same. Also please specify if the attached connection is correct.

    Hi Gopika,

    Please provide what voltages you plan to apply to REFT/B pins, the attached schematic doesn't indicate.

    Otherwise, this looks to be correct. Unfortunately, this device is very old and we don't have anyone left from the team or even any eval brds to verify his circuit.

    Is there a reason you need to use an ext ref circuit? Instead of the internal reference?

    Thx,

    Rob
