It adopts advance single-chip microcomputer control technology, so it has high accurate, resistance disturb, can completely accommodate with controllable circuit;

Digital potentiometer compare to mechanical potentiometer, its advantages are: controllable resistor by program, shock proof, long service life, resistance pollution etc; It is a semiconductor integrated circuit product which have configuration and data register with high accurate, and it without mechanical wear, data can be read, easy to control by soft wear, easily to install because its small size, it suitable for audio system; so already widely successfully have been used in automatically testing controlling intelligent devices, and consumable electronic products and various important relevant fields;

Can be chosen different value according to demand:

A:0~5K  adjustable

B:0~10K  adjustable

C:0~50K  adjustable

D:0~100K adjustable

E:0~200K  adjustable
