DollaTek X9c104 digital potentiometer module

• The change of digital potentiometer are stepwise or incremental, resistance changes linearly.
• X9C104, for example, resistance range r 40 ~ 100 k, which is divided into 100 order, the increment of each tapping point as 1010 r.
• Temperature compensation function: the resistance of the error between the endpoint: + / - 20%;
• Resistance high resolution: 1%.
• 0

DollaTek trademark Reg.NO:013726393 Among various kinds of bridge circuit, in order to adjust the bridge balance, must to repeatedly adjust potentiometer, can make a bridge to balance, in use process, when the potentiometer is vibration, shock, temperature, humidity and so on the external environment factors, the location of the potentiometer and parameters will be changed, the system pointer to change, to make the system achieve the original state, must be adjusted, it caused a lot of inconvenience for use, therefore, in the bridge arm of the circuit using array potentiometer and digital technology, not only overcome the above shortcomings, can also greatly improve the precision of the system. X9C104 is 100 order digital potentiometer, specific X9C102/103/104/503 series, resistance range of 40 r ~ 100 k, X9C104 internal resistance array consists of 99, in between each unit and two endpoints are the sliding unit tapping point, the position of the sliding unit by CS, U/D and INC three input control, but the location is selected, can be stored in a non-volatile memory, after the next to electricity to call. Working voltage (V) : 5 The total value (k Ω) : 100 The terminal voltage (V) : - 5 ~ 5 Tap the number: 100 Interface: CS and U/D, INC Mode of resistance increase: linear Working current (mA) : 3 Encapsulation/temperature (℃) : 8 soic / - 40 ~ 85 Position description: tap off electricity automatically saved Package Includes: 1x DollaTek X9c104 digital potentiometer module
