I have a hardware question.
In my application i want to sample a signal from hall effect sensor in the windows from 0.5V to 4.5V.
To improve the fidelity of the ADC i want to compress the dynamics of the ADC, and put the Vref @ 4.8V. My question is: My connection in the attached document is right? Or a voltage resistor divider is better?
Thanks to everybody in advance for our reply.
