A resistor is characterized by an always constant resistive value. With the same applied voltage, it will always pass the same amount of current. The potentiometer, on the other hand, is an electronic ...

In the previous part of this article An Isolated Potentiometer, Part 1, the current sources used in the isopot – both Howland and op-amp V/I – were explained. We now get to the heart of the isopot ...

We connected the DS1801 to our Bus Pirate universal serial interface tool as shown in the table. We used the Bus Pirate to demonstrate this chip, but the same basic procedures apply to any ...

In many system applications, it becomes necessary to adjust a switched-mode power supply (SMPS) output voltage within narrow limits in order to remove tolerances and drops in the power path, verify ...
