X9C104 Digital Potentiometer module helps you simulate the mechanical control of a potentiometer.
- contains 99 series-related resistors.
- With a microcontroller, you can control the module and select the place where the center pin of the “potentiometer” is connected, anywhere in the 100 points available (at the ends of the group or between the resistors).
- in addition the X9C104 potentiometer consists of inserting a hundred resistors with a 1K ohm value.
- more over With the pins we can select the number of resistors we want, so we can digitally vary the resistance of the potentiometer.
- furthermore also the device dissipates a power of 10 mW and supports resistors with a maximum current of 4.4 mA.
- in addition this module has varied applications, can be used as resistive divider, variable resistance, these are used in different schemes with operational amplifiers or other analog circuits.
Features
- The X9C104 digital potentiometer module is a variable resistor whose resistance value can be set digitally by a microcontroller. I
- in addition it consists of 3 output pins (RH، RW و RL) which can replace a mechanical potentiometer which has 3 pins.
- This module has 99 resistance components and its resistor is controlled by a 3-wire interface.
X9C104 100K Digital Potentiometer Module Pinout
This sensor has 10 pins:
5 pins on the left side:
- VCC: Module power supply – 5V
- GND: Ground
- INC: Changing resistor command
- U/D: UP / Down. Adjusting resistor
- CS: Chip Select. Active LOW
5 pins on the right side:
- VCC: Module power supply – 5V
- RH: Resistor High
- RW: Regulated Resistor
- RL: Resistor Low
- GND: Ground
in addition thid device dissipates a power of 10 mW and supports resistors with a maximum current of 4.4 mA.
Be careful not to design a circuit in which this current exceeds this maximum, otherwise you may burn the potentiometer.
more over Most of the times, potentiometers are used to generate variable reference voltages and there is no need for significant power consumption, so the maximum current limit of 4.4 mA is sufficient.
in addition you can read more specifications in the device datasheet.
These digital potentiometers are for example used in the industrial field.
For example, analog signals generated by various sensors have to be calibrated using Wheatstone bridges made up of variable resistors.
Using digital potentiometers and microcontrollers, signal self calibration systems can be implemented.
You can use the X9C104 module to build a software controlled voltage source or a variable amplifier amplifier controlled by the Arduino plate.
