Digital Potentiometer Circuit with IC X9315

In this article we investigate the IC X9315 which is actually a solid state digital potentiometer and could be used exactly like a mechanical potentiometer, but through logical supply inputs. The  IC X9315 from Intersil,  is a digitally controlled solid state potentiometer, which internally possesses an array of resistors, wiper switches, a controlling system, and a non-volatile memory section. The IC utilizes a 3 wire interface for controlling the various positions of the wiper, and the potentiometer function is implemented through the array of resistors which are 31 numbers of resistive network, associated with the wiper switching network. The entire array along with the end points of this resistive network are all integrated with the wiper network such that the wiper is able to access any point of the resistor array for executing the corresponding values of the potentiometer output through the 3 wire interface. The CS, U/D and the INC pinouts of the IC actuall...

Get The First Simple Step To Learn Electronics

Electronics for beginners is a topic I love. There are too many people out there trying to preach that electronics is hard. Of course it takes time to become an expert. But you can start having fun, and build useful things pretty much right away. And it’s easy!     Wouldn’t it be cool to make something like a remote control or an amplifier? Or maybe something more advanced like a quadcopter or a mobile phone? Do these steps, and you will be well on your way to building whatever gadget you are dreaming about. Step 1: Get An Overview Of The Basics     The first step to take, is to get a simple understanding of the basic concepts in electronics for beginners. Voltage, Current and Resistance Current is measured in Amp or A Voltage is measured in Volt or V Resistance is measured in Ohm or Here is a nice illustration: Learn more about the basics of current, voltage and resistance. Schematics     Schematic diagrams are like recipes for el...
