Working Principle of DS1845E-100+T&R
The DS1845E-100+T&R is a digitally programmable potentiometer. To understand how the device works, we must first understand the principles of a potentiometer. A potentiometer is a device consisting three electrical contacts (terminals), a rotating contact (wiper), and a resistive element. The resistive element is often a strip of graphite or a strip of resistance wire.
The DS1845E-100+T&R operates by converting the analog signal from the rotating contact into a digital code. The 10-bit binary coded resistance information allows for 1024 possible positions. In order to convert the analog signal into its digital code, the device uses an on-chip digitally programmable resistive ladder. This ladder is used to create different voltage levels across the resistive element that correspond to the position of the wiper.
The device is able to drive multiple loads without additional components by using a buffered control output. This feature allows for a wide range of applications including direct control of liquid crystal displays, mechanical systems, and other devices.
Conclusion
The DS1845E-100+T&R is a digitally programmable potentiometer that is commonly used in a variety of applications. It is able to operate in a wide range of temperatures and can be used to control multiple loads without additional components. This device provides 10-bits of binary coded resistance information which allows for a total of 1024 possible positions. Understanding the application fields and working principles of the DS1845E-100+T&R can help designers make the most of this versatile device.
