ADS7924: Addressing Issues

Part Number: ADS7924

Team,

I have a customer designing with an ADS7924EVM, and they are having some problems. It sends address 50 instead of 49 when the address jumper is open. They are also using a SolidRun SOM which has an ADS7924 set to address 48. They can communicate and measure voltages with address 48, but they don’t know why the EVM is returning address 50. Any ideas?

  • Hi Carolus,

    There is an EEPROM on the ADS7924EVM that looks like it is at address 50h, the actual ADS7924 should only respond to address 48 or 49. Can you verify all the power rails are present?

    Tom,

    The customer has gone silent on this one, so I would say this more than likely fixed the issue. Lets mark this as closed, and I can repost if necessary.
