product description
In various bridge circuits, in order to adjust the bridge balance, the potentiometer must be adjusted many times to make the bridge balance. During use, when these potentiometers are subjected to vibration, shock, temperature, humidity, etc. The position and parameters of the potentiometer will change under the influence of environmental factors, which will cause the system index to change. To make the system reach its original state, it must be adjusted. This brings a lot of inconveniences to using. For this reason, in the bridge arm circuit of the bridge, The use of array potentiometers and digital technology can not only overcome the above shortcomings but also greatly improve the accuracy of the system.
X9C104 is a 100-step digital potentiometer, specifically X9C102/103/104/503 series, the resistance range is 40R~100K, X9C104 contains 99 resistor arrays, which are slid between each unit and on both ends The tap point accessed by the unit and the position of the sliding unit are controlled by the three input terminals of CS, U/D, and NC. Once the position is selected, it can be stored in non-volatile memory and can be recalled after the next power-on.
Performance parameter
Working voltage (V): 5
Total resistance (KΩ): 100
Terminal voltage (V): -5~5
Number of taps: 100
Interface mode: CS, U/D, INC
Resistance increase method: linear
Working current (mA): 3
Package/Temperature (℃): 8SOIC/-40~85
Description: The tap position is automatically saved when power off
Function brief
The changes of the digital potentiometers are stepwise or incremental, and the resistance changes into linear changes.
For example X9C104, resistance range
40R~100K, divided into 100 steps, the increment of each tap point is 1010R
With temperature compensation function: resistance error between terminals: ±20% ;
The sliding end position data can be stored for a long time, the time is 100 years;
The resistance resolution is higher: 1% .
