Analog signal 5V to A0

Post by 07zoomt »

What is the recommended way to do this? As far as I understand the signal should be 3 V max.

Is al voltage divider with 67 kOhm and 100 kOhm sufficient - A0 over 100kOhm?
Do I need to add a capacitor 0.22F in Parallel to A0 and GND?

Thanks

The voltage divider is enough
