I am using the ADS8528 in HW configuration mode with internal ref 2.5 (x2) and with serial output.
All 8 channels have inputs (see schematic)
When reading the output data - there appears to be a random influence on other channels.
Specifically, when there is a negative voltage on channel 3 (B0), it adversely effects channel 5 (C0).
If the B0 has a positive voltage, C0 is unaffected. It is as if there is stale data internally from shifting ADC (B) data (parallel to serial?) out and moving in ADC (C) data.
The influence seems to only be the first byte - as if the logic high bit level cannot discharge fast enough.
I thought the source impedance for channels 5, 6, 7, 8 could be the problem but have injected voltages from signal generator and still see the issue.
