I "NEED" to monitor a battery voltage which might in some rare condition exceed 24Vdc.
To avoid damaging the analog input of the RUT955 I wish to use an external potential divider circuit like this:
I presume that the ADC input in the RUT955 has an impedance (which would be in parallel with R2) and so cannot select the divider values without knowing this.
Please can you give the "resistance" of the Analog input, so that I can calculate the potential divider resistor values?
Others might find it useful if the wiki were updated with this information too.
