| 14.4V ground reference for ADC |
| << < (20/33) > >> |
| Arjunan M R:
So i think i will stick with this voltage reference. |

I am going to still add a 10µF tantulum and 100nF ceramic cap to input and output for extra stability and noise reduction. |
| Arjunan M R:
IT requires a 100nF cap. for supply bypass. |
| Simon:
Yes just follow the datasheets recomendations. You are drawing µA not mA so you don't need to go heavy handed on the output capacitance. Filtering it is not a bad idea. |
