Working Principle

The DS1844-100+ is a 3-terminal, 24-position, stainless steel linear potentiometer. It consists of a resistance ladder that is divided into 24 resistance steps. A positive voltage is used to select the resistance steps , while the other terminals connect to the resistance ladder. The resistance between the terminals is adjustable with the positive voltage.

The DS1844-100+ offers a great solution for analog applications that need adjustable resistance. The voltage steps determine the resistance of the ladder, which means that its resistance can be setup and changed with the same voltage. The three terminals allow the resistance to be adjusted from low to high resistance without having to disconnect and reconnect the terminals. This makes the DS1844-100+ a great tool for situations where constant adjustment is required.

The device also includes a built-in circuit for overcurrent protection, which prevents it from overloading and damaging the system. Additionally, the DS1844-100+ has a temperature compensation feature that ensures it remains accurate in a wide range of temperatures.
