| How to measure the voltage across a potentiometer ratiometrically |
| << < (4/4) |
| jbb:
Sorry, was that 1000 Ohm max or 5k max? I think we can do this without analog multiplier chips or choppers. The scheme I’m thinking of will drive the sensor with a constant current that is proportional to the supply rail. Do you have any maximum current or voltage or power specs for the sensor (variable resistor)? |
