Hi folks! I'm using a TMP36 plugged into the ADC on a Netduino, and the signal is pretty noisy:

The spikes in there are my concern; they tend to make a bit of a mess of readings. I can oversample, of course, and that works fine, but I'd really like to clean them up a little bit with hardware.
In my (limited) understand and reading, I know that a capacitor resists changes in voltage, so I tried varying capacitors between the `Sout` and `GND`, including 0.1µF,...
