I2C bus digital potentiometer AD5242 was used as core of digital alternating current parameter multi-function meter, it has a point, two point and multiple point sampling arithmetic.
The performances of linearity, function conformance, and short circuit between turns have the direct effect on the applications of the potentiometer in automatic control and instrument systems.
Plastic knobs and buttons are currently widely applied in all kinds of electronic, electric, instrumentation, sound, and mixer devices; they mainly function to position andfix potentiometer switches.
