A resistor is an electrical device that resists the flow of electrical current. In the digital era, we can find a variety of “digital resistors” for our everyday applications. This article is about ...

Fig. 1. DACs have traditionally incorporated an output buffer while digital potentiometers have not. Digital potentiometers allow you to adjust an analog voltage while DACs adjust current, voltage, or ...

Digital potentiometers are digitally controlled variable resistors that can be used in place of their functionally equivalent mechanical counterparts. While digital potentiometers offer comparable ...

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 ...
