ADC for MKL series

Hi,

I am working on MKL16 series for a product using battery. I want to monitor Vbat but MKL series does not provide Vbat pin and internal ADC channel for this purpose. So I think I should use normal ADC to measure Vbat. Do you have any recommand for design to reduce leak current?

Thanks,

Hello,

Yes, there has no backup power domain for KL16 and requires the processor to remain powered in a very low leakage state, usually using a low power 32khZ oscillator rather than crystal.
