Wire wound potentiometers
This potentiometer comprises of several rounds of wire wound around the shaft of the non-conducting material. In this case the slider, connected to the body whose displacement is to be measured, moves on the potentiometer track and it makes contacts with successive turns of the coil.
Carbon film potentiometers
The carbon film potentiometers are formed by depositing carbon composition ink on an insulating body, which in most of the cases is phenolic resin. This is one of the most commonly used materials for the pots that is quite cheap and has resolution better than the wire wound potentiometers. They have reasonable life and tolerable noise levels.
Plastic film pots
These pots comprise of the specially impregnated plastic material having resistance characteristics that are controlled properly. They have very good life, resolution better than the wire wound pots, and low noise.resolution is limited by size of particles, hence their accuracy is very high.
Digipots are typically available with linear or logarithmic tap points. In addition, Maxim offers some further variations of the basic digipot. Nonvolatile digipots retain their last programmed wiper position when the power supply is switched off. OTP digpots set the wiper’s power-on reset (POR) position to a user-defined value.
