Hello!
We have two ADS8331 EVM Rev. A. Both cause huge spikes (1 Volt) in the first (of the four) analogue channels. The spikes are caused by the CONVST signal in auto channel select mode.
The spikes appear after each forth CONVST (using 4 channel auto select mode), approx 200 ns after the falling edge of CONVST.
Although it doesn't seem to influence the conversion, I don't think that it is regular behaviour. Did anybody make similar observations?
Best regards,
Markus
