AMC1303M2510: spikes in measurements with the AMC1303M2510

Part Number: AMC1303M2510
Other Parts Discussed in Thread: AMC1303

Hi,

We have a problem with the AMC1303M2510DWV.

The DOUT of the Delta-Sigma sometimes is 1 (high) for a short time (about 0.2ms), but the input signal is significantly smaller than 250mV. So we get spikes in our measurements.

Is it possible that this is because of problems with the AVDD (EMI)?

We have 100nF + 10µF verry close to the AMC1303M2510DWV, but other ICs use these voltage level too.

Many thanks in advanced.
