Filter & decimation implementation on AD7401

Hello everybody! We have chosen the AD7401 Sigma Delta modulator for our project, translated the Verilog code given by the datasheet into VHDL and are now confused about the results of the simu...

You must misunderstand what I meant.I measured the voltage is uncertain, of course, I want to say is that when I measured the voltage to a constant value, the AD7401 measurement result should be a value fluctuating within a narrow range.My situation now is that it measured the AD value is very unstable, the fluctuation range is too large.

I will take your advice, thank you.

I need to finish the work with two AD7401 which were measuring the 800V series battery voltage(Precision resistor divider less than 200 mv to put in the AD7401) and shunt (Specification 600A-75mv) current sampling voltage.
