    Hi Eren, 

    The device will act as a voltage divider with the wiper output ranging from HA to LA. You will not get the full 8-bits of resolution because you are not using the full range, but yes, you can use the device as shown in your circuit. Make sure your I2C controller will work with 2.5V logic. 

    Best,
