We are conducting gas detection, using gas reaction current and DDC112 to collect data. The phenomenon is: testing with gas concentrations of 500 and 2000, and after inputting the gas concentration of 2000, injecting the gas concentration of 500 again. The final result shows that the feedback current is different, with deviation, and the value is less than the previous gas concentration of 500
CLK frequency is 12M, CONV frequency is 20ms
