ADS8688EVM-PDK: Problem with updating the EEPROM after swaping out the 8688 with a 8698

Other Parts Discussed in Thread: ADS8688, ADS8678, ADS8698

Greetings,

We at Draeger are interested in evaluating the 8698 (18-bit ADC), so we desoldered the 8688 and populated the pin-compatible 8698

Following the EVM user guide, I moved the write protect switch to enable writing the EEPROM, and then powered on the EVM, and started

the GUI.

The GUI (v1.1.0) comes up fine, and shows ADS8688 in the upper right corner.

Tools -> Load EEPROM

However, it only gives me two options, ADS8678 and ADS8688

No ADS8698 option?

What am I missing, or doing wrong?

Thanks

Ken

Hi,

I have fixed the above issue by un-installing the EVM GUI, and re-installing a different EVM GUI I got from a co-worker.

Both installers had the exact same name (Setup_ADS8688_EVM.exe) but resulted in a different GUI program to be installed.

The old one was "ADS8688 EVM", the new one which now works is "ADS86x8 EVM", notice the "x" in the title

I could not find any reference to this "x" version on the TI support site?

Thanks

Ken

Hi Ken,

Thanks for pointing this out. I'm not sure where the "x" version is, perhaps it is an older version of the GUI. I will check with our software team.

Best,

Samiha
