Description

Product selling point: 1. Using high-quality materials, the quality is guaranteed 2.V3 with ESD electrostatic protection circuit, the module is more stable 3.V3 supports 5-12V wide voltage power supply 4.V3 adopts PH2.0 high quality SMD port 5. The module requires the user to program the control port to make the digital potentiometer work, which can be used to modify automation equipment, audio equipment, household appliances, etc. Parameter: Working voltage: DC 5V-12V Rated power: 1mW Working current: 3mA (maximum) Wiper current: lmA (max) Waiting current: 500uA (maximum) Note: X9C103 is a low-power CMOS device, pay attention to electrostatic damage to the device, especially after replacement, it must be cooled to room temperature and then powered on The middle tap of the potentiometer slides between 0-10K (0-100K) in a total of 100 steps (the typical impedance of the potentiometer sliding end is 40 ohms) The VL and VH ports of the digital potentiometer correspond to the low-side and high-side of the sliding rheostat, respectively, allowing an input voltage range of -5V to +5V The VW port of the digital potentiometer is equivalent to the movable end of the mechanical potentiometer, which is controlled by the control port. The typical value of the series resistance of the sliding end is 40 ohms. Module debugging: When the digital potentiometer is used for the first time to test its quality: The resistance value of the resistance terminal measured by the ordinary multimeter is usually abnormal. This is because of the special internal structure of the digital potentiometer, and the working state of the potentiometer needs to be measured by the voltage division method. Take the DC 5V voltage and add it to the VH and VL terminals, measure the voltage of the VL port and the VW port with the voltage range of the multimeter, and change the resistance value of the potentiometer after the potentiometer works. Instructions for use: The digital potentiometer module comes with a test program, and the program code is C language code, which is written in modules. The code includes: the main function, the display sub-function, the button sub-function and the header files of each module. You can use KEIL4 to open the source code for testing and learning. Package Included: 1* V3-10K module 1* Terminal wire
