Hello,
I'm abit confused... while the reference is +/-0.6V and absolute ratings are not to go below VSS=0
so is it SAFE to measure -0.5V with the ADC?
it looks like we only use half the span of the ADC if we restrict to 0..+0.6V
Another question - if we use GAN1/4 then 1V reads as 0.25V by the ADC
so in such case, can we input -2V (read as -0.5V by the ADC when using gain=1/4)?
Is it the same answer for the nRF9160 and nRF9161?
the AI answer is not so clear (see below)
thanks
Ohad
