Detailed explanation of the three pin connection method for multi turn precision adjustable potentiometers
1、 Introduction to Multiturn Precision Adjustable Potentiometers
Multi turn precision adjustable potentiometer is a commonly used electronic component used to adjust linear voltage and current in circuits. It has high accuracy, reliability, and is suitable for various circuits, and is widely used in the electronics industry.
2、 The connection method of the three legs of a multiturn precision adjustable potentiometer
The three legs of a multi turn precision adjustable potentiometer are the middle leg, sliding leg, and fixed leg. According to different needs, the middle foot and sliding foot can be connected to the circuit separately, and the fixed foot is usually used for power or ground.
A. Single circle connection method
The single loop connection method is to connect the sliding foot and the middle foot together, and fix the foot to ground or power. This connection method is suitable for single voltage circuits, such as audio amplifiers, power amplifiers, etc.
B. Double circle connection method
The double loop connection method is to divide an adjustable potentiometer into two parts, connect the two fixed pins together, and at the same time connect the middle pin and the two sliding pins to two separate circuits. This connection method is suitable for circuits that require two different voltages or currents, such as power amplifier front-end circuits.
C. Three circle connection method
The three circle connection method is to divide an adjustable potentiometer into three parts, connect two sliding pins and one fixed pin into one circuit, and at the same time connect the middle pin and the other fixed pin to another circuit. This connection method is suitable for situations that require two different voltages or currents, such as audio frequency EQ circuits.
