We are using ratiometric voltage sensors for an application, by selecting the reference voltage (A or B) on the controller input, does this automatically offset the VIN with the VREF supply fluctuations?
We know that because the sensors are ratiometric the supply to the sensor will cause the signal emitted from the sensor to change slightly. We have achieved this using code in the application, however i'm just checking the controller does not compensate for this automatically without the need for user configured code? I would imagine it does not do it automatically because there is no option to select its a ratiometric or normal regulated sensor connected to the VIN.
Perhaps this could be a feature we see in a future IQAN Design? I know we would find it useful instead of having separate code. Provided of course the variation % on a ratiometric sensor output is the same for different manufactures of sensor, if they are different, maybe an option to enter some values?
