CS5467 ADC data is noisy.

ravi1488 · Mar 22, 2014

Hello,

I am using CS5467 for the AC signal sensing. I want high speed output ( around 10 Hz) with minimum 12 bits resolution. The problem is that , the output is very noisy. What should I do for that.

I have implemented all the required filters.

Have anybody used that IC ???

Thanks

And these "required filters" relate in what way, to the
noise at the input? Spectrally? What does analysis of
your digital "noise" tell you?

Thanks for the reply.

I have attached a schematic of CS5467.

I am using with 12 bit resolution. The adc counts are not stable. Even I am not getting good stable 10 bit data. View attachment Input Schematic.pdf

Hi.. Can you post the complete schematic.
