Hi Guys,
I want to use below circuit for battery voltage measurement for two series 4.2V Li Ion battery as per below.
Could anybody body help me out here ?
My understanding was :
Without opamp : Divider leakage current = 89uA
With opamp : pA since opamp input impedance is high
Now my question is if i use opamp as a buffer will reduce the battery leakage current ?
In below circuit , will divider use current from supply or it wil still take from battery ?
Regards,
