Dear Sir, I'm using a AD7865-2, have some problem convertion results. There is a simple Low pass filter on the Vin of AD7865-2. But Resistor value is Zero ohm, and Capacitor is 0.01uF. In this case, the conversion result is good. But in case of that resistor is 1k ohm, the conversion result is lower than that of zero resistor. What is the problem? Please let me know, if someone knows the reason for that. Thanks a lot.
