DS3904

How to Perform DS3904 Digital DIP Switch Resistor into High-Impedance Mode Circuit

The advantages of using a digital DIP switch instead of a conventional mechanical one is that the digital offers small size and better security. The DS3904 is one example that contain three digitally controlled nonvolatile (NV) variable resistors. It has the capability to set the variable resistors into high-impedance state. High impedance mode of DS3904 […]
