The DS1867E-10+ is one of the latest and most innovative digital potentiometers, part of a family of devices offered by Dallas Semiconductor. This family has been designed and manufactured to provide users with an easy and straightforward way of controlling their equipment or systems that require a variable voltage setting or an adjustable resistance value.
The application field of the DS1867E-10+ is wide and it can be employed in a great many different applications. It can be used in scenarios where adjusting a voltage or current level is required (for example, for light, sound, and temperature control) or for the adjustment of a resistance value to set the perfect frequency or pulse-width setting for a specific device. The DS1867E-10+ can also prove useful in applications that require a multiple-level electrical setting, such as motor speed control, and can also be used for modifying gain settings for particular circuit parameters.
In terms of its working principle, the DS1867E-10+ digital potentiometer is composed of two main elements: the potentiometer element and the digital control circuitry. The potentiometer element can be considered the analog part of the device and it is the element responsible for generating the resistance changes. It is basically composed of three resistors that have been put together in series and are connected to three terminals - a midpoint, an upper terminal and a lower terminal. The midpoint terminal is where the voltage adjustment is made, while the upper and lower terminals are used to electrically control the midpoint terminal in order to generate the resistance changes.
The digital control circuitry is where the real power of the DS1867E-10+ lies. This is because the digital control circuitry is responsible for converting the electrical signals coming from the external control source (e.g. a computer) into a series of digital instructions that are then passed on to the potentiometer element. This allows for a much more precise control of the resistance setting compared to using a mechanical potentiometer due to the action of the digital bits used.
The feature richness of the DS1867E-10+ digital potentiometer is what makes it so attractive when compared to other applications. It has been designed with a remarkable set of features such as low power consumption, an adjustable voltage range, and an adjustable resistance value which can be set from 0 to 127 levels. In addition, the device also features a non-volatile memory that can store up to 64 user-defined settings, allowing for easy and quick access. Finally, the device also comes with over-temperature protection, making it reliable and safe for usage in all types of industrial applications.
