Product Description:
In various bridge circuits, in order to adjust the bridge balance, potentiometers must be adjusted several times in order to make the bridge balance, in the process of use, when these potentiometers are affected by vibration, shock, temperature, humidity and other external environmental factors, the potentiometer position and parameters will change, resulting in system indicators change, to make the system to the original state, 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 to overcome the above shortcomings, but also can greatly improve the accuracy of the system.
X9C104 is a 100-order digital potentiometer, specifically x9c102/103/104/503 series, resistance range of 40R ~ 100K, X9C104 contains an internal array of 99 resistors, between each unit and two endpoints are tapped points visited by the sliding unit, the position of the sliding unit is controlled by three inputs CS, U/D and INC, but once position is selected, it can be stored in non-volatile memory and can be recalled after the next power-up.
