Hi,Andrei,

 

Reference your design AD7982.v.Modified to support for multiple multiplexed channel applications.The attachment is a the ad7982 verilog.v file.Produced by a the LX9 board of USER_CLOCK 60 MHZ, available to adc_clk_i.

 

+5 V input, reading:

+10 V input, reading:

Reading is correct.However, the sign bit is "1", sometimes.I do not know the cause of the error?

 

Regards,
