Hi All,
I currently have a two 5 volt fans wired in series controlled with a analog rheostat (https://www.digikey.com/product-detail/en/cts-electrocomponents/026TB32R500B1A1/CT2153-ND/203774). The amperage of each fan is 0.3mA and ohm rating for a fan is ~50 ohms. I would like move this design to a push button potentiometer. (one buttom increases fan speed and other decreases).
As I am new to the digital pots, I am not understanding the wiper ohm rating on a digital pot as well as the overall resistance rating.
Thank you in advance for any help you can provide.
