we are developing a new product and we want to add some extra features as battery level indication.
For this reason I plan to add to our board a device (digital potentiometer?) that is going to "transform" the measured voltage from the battery to Ohms. I need the Ohms as input in order to set battery alarm indication.
So we need a device that it will measure voltage from 3 - 5,5 volts and transform it to some KΩ. Is digital potentiometer suitable for our application? How about AD5116?
Are there any other products (preferable not SMDs) that are suitable for our application? Thank you very much in advance. I am looking forward for your response.
