... be seen that the voltage is 2.5V. However the voltage divider formula can be applied: VRX = (VSUPPLY/ RTOTAL) * RX VREQUIV = 5V/12k * 6k = 2.5V To cross check if this is correct we use the calculated step voltage of 0.625V per step and multiply it by the binary count 1002 or 4: 4 * 0.625V = 2.5V ...
