Hi,
In relation to the previous question, I am experiencing a similar problem due to the RC time constant being too big and my internal sampling capacitor not discharging quickly enough, hence affecting the value of my subsequent measurement.
I was wondering if there is a similar 4-channel ADC in TI's ADC family that mitigates this issue with a smaller value of the internal sampling capacitor. Due to board size constraints, I do not think I have the luxury of putting an input buffer for each of the 4 channels I am using.
Other suggestions on improving the performance also welcome.
Regards
Ben
