Operation
Figure 1. GUI for DPOT Control
There are three methods to adjust the value of the TPL0501A/B. Start by clicking one of the buttons
circled in GREEN to select the corresponding TPL0501 device.
To adjust the tap value directly simply click the box that says tap and you will be prompted to input a tap
value between 0 and 127. After typing in the desired value press enter and the tap value will be sent to
the TPL0501A and the GUI will reflect the value you just entered.
To adjust the TPL0501 by inputting a wiper to low terminal resistance, click the box that says W-L
Resistance. You will then be prompted to input a value between 0 and 10,000 ohms; press enter after you
have input a value. The GUI will use the theoretical resistance values to find a tap that is closest to the
value that was input.
NOTE:
All W-L resistance values are theoretical; the actual value will be within 20% of the displayed
value.
