Description
The CNV output voltage is 3.6 V, but the LTC2320 datasheet specifies that "this input must be driven at OVDD levels", which is 2.5 V. So the CNV voltage needs to be changed to 2.5V.

Research direction
No file or test is named in the issue. Start by locating the schematic or hardware entry point that defines the LTC2320 CNV output, then compare its configured voltage with the datasheet's OVDD requirement. Done means the CNV output is set to 2.5 V and the relevant design validation still passes.
