Description
In various bridge circuits, in order to adjust the bridge balance, the potentiometer must be adjusted multiple times to balance the bridge. During use, when these potentiometers are subjected to vibration, shock, temperature, humidity, etc. Under the influence of environmental factors, the position and parameters of the potentiometer will change, causing the system index to change..To make the system reach the original state, it must be adjusted, which brings a lot of inconvenience to the use. For this reason, in the bridge arm circuit of the bridge The use of array potentiometers and digital technology not only overcomes the above shortcomings, but also greatly improves the accuracy of the system..X9C103S is a 100-order digital potentiometer with a resistance range of 0~10K. The X9C103S contains 99 resistor arrays inside. There are tap points accessed by the sliding unit between each unit and at both ends. The position of the sliding unit is CS, U/D and INC are controlled by three inputs. Once the position is selected, they can be stored in non-volatile memory and can be recalled after the next power-on..The changes in the digital potentiometer are stepped or incremental, and the resistance changes linearly..For example, X9C103S, with a resistance range of 0~10K, is divided into 100 steps, and the increment of each tap point is 1010R. Temperature compensation function: resistance error between terminals: +/- 20%; sliding position data can be saved for a long time; high resistance resolution: 1%.
