Hi,

I use the ADC to sample battery level once in a while using the internal 1.24V Vref.

How do I completely turn off Vref in between samples to conserve power ?

Thanks

You don't have to turn off ADC. If you don't do ADC reading, there is no power consumption on ADC circuit.

Thanks YiKai. Note that there are ADC (among other peripheral examples) available from the product page: www.ti.com/.../swrc257
