LTspice is a powerful tool, but it notably lacks a built-in potentiometer component. To simulate variable resistance, you must either build your own using two resistors or download and install a custom subcircuit and symbol file. Where to Download LTspice Potentiometer Models
Open your LTspice installation directory (often in Documents/LTspiceXVII/lib/ ). Move the Files: Place the symbol file ( .asy ) into the sym folder. ltspice potentiometer model download
Offers a streamlined SpicePot ZIP file with cleaned-up code for easier use. LTspice is a powerful tool, but it notably
Place two resistors (e.g., R1 and R2) in series. Set R1's value to {Rtot * Wiper} and R2's to {Rtot * (1 - Wiper)} . Move the Files: Place the symbol file (
Several reliable community sources provide free potentiometer libraries that include both linear and logarithmic tapers:
Use the .step param directive to vary the wiper position during simulation. For example, .step param Wiper 0 1 0.1 will simulate the circuit at 10 different wiper positions from 0% to 100%.
