Hi,
I'm working on an application that uses ADS1243, with 3 differential inputs. In long-running tests of 9+ hrs, random spikes are observed 3-4 times, on every channel. The spikes occur at different instances on different channels. The deviation from normal range is upto ~150,000. The channels are read cyclically, at an interval of 100ms, with data rate of 15Hz. The DRDY line also indicates data ready when data is read. The spikes are observed even for intervals of 85ms, 130ms, 150ms, though at higher intervals (> 130ms), the deviation is seen to be reduced to ~5000 and the spikes spread out slightly in time. Any help in troubleshooting is highly appreciated.
Thanks in advance.
