Hi All,
I'm currently using the MCP3008 ADC to measure some variable resistors. These resistors are connected to a 4.096v VRef and their output (as a voltage) is connected to an input of the MCP3008.
What I would like to do is find a way that I can use the MCP3008 (if possible) to measure the voltages of some other DC sources (for example; the voltage of a battery source).
The battery voltage may be up to 48v and I was first thinking of a simple voltage divider but this wouldn't work as it would be essentially a short-circuit on the battery. So I need a way to divide down the battery voltage into the range of 0-4.096v with a resolution of 0.1v (more would be great but not necessary) and to do it in a way that would be safe from short-circuit and burning out the components.
Thanks in advance
Anubis.
