flexray transceiver.Introduction to the functional application of digital potentiometer sensor

　　Resistance and potentiometer sensors are indispensable components of various electronic devices. Driven by the demand for chip resistors in the global mobile communications, computers and peripheral, consumer digital and automotive electronics industries, local suppliers in China have increased their investment in potentiometer sensors, especially the rising demand for small resistance and potentiometer sensors for portable electronic devices. I believe that China's resistance and potentiometer sensor industry will encounter unprecedented power and opportunities in the future.

　　Potentiometer sensor, the Taiwanese like to call VR, Hong Kong people call: turbine. Foreigners can only call it: potentiometer. There are many people called: adjustable resistance, because the potentiometer sensor is a resistance that can adjust the volume, so it is referred to as adjustable resistance. Also called: fine tuning, the principle is the same.

　　Digital potentiometer sensor can also be called CNC programmable resistor, it is a new type of CMOS digital and analog mixed signal processing integrated circuit instead of the traditional mechanical potentiometer sensor.

　　The digital potentiometer sensor generally has a bus interface and can be programmed by a single chip computer or a logic circuit. It is suitable for the construction of various programmable simulator components, such as programmable gain amplifier, programmable filter, programmable linear voltage regulator power supply and tone/volume control circuit, which truly realizes the new design concept of "putting the simulator on the bus".

　　The digital potentiometer sensor adopts the numerical control method to adjust the resistance value, with flexible use, high adjustment accuracy, no contact, low noise, not easy to stain, anti-vibration, anti-interference, small size, long life and other significant advantages, can replace the mechanical potentiometer sensor in many fields. At present, digital potentiometer sensors are rapidly promoted at home and abroad, and are widely used in testing instruments, PCS, mobile phones, household appliances, modern office equipment, industrial control, medical equipment and other fields.
