Rotary Potentiometers and Rheostats are two of the most common instruments used to measure resistance and voltage readings. The SPPG048S102U is a single-turn rotational IC potentiometer specifically designed to facilitate the measurement of resistance or voltage. The working principle and applications of this IC are discussed below.

Typical Application Field

The SPPG048S102U is mainly used in automotive, medical, consumer and general-purpose applications such as remote control, audio equipment, temperature control, as a security feature, industrial device operation, and even in some toys. This single-turn potentiometer has a wide range of applications because of its low contact thermal resistance, low TC (Temperature Coefficient), and fast response time. It can even be used in combination with other types of sensors to detect feedback signals for accurate positioning and speed control applications as well.

Working Principle

The working principle of the SPPG048S102U is based on the physical property of electrical resistance. A low value resistor is placed between the two terminals of the unit and a knob is used to rotate the shaft. The resistor\'s resistance changes when the knob is turned. This change in resistance is detected by an analog to digital converter. The digital output is then sent to the processor, which is then used to control the output or actuate the position of the device.

The resistance value goes through a range of 0 ohms to a maximum value defined by the design of the potentiometer before the resistance reverses direction and begins to decrease. This range is determined by a resistive convention created by two resistors in parallel, with the resistance value of each resistor being determined by the knob position. The maximum resistance is equal to the sum of the two resistors. The SPPG048S102U is completely analog and the resistance measurement range is 0 ohms to 2k ohms.

Benefits

The SPPG048S102U single-turn IC potentiometer is designed with low contact thermal resistance, excellent linearity, low TC and simple construction. Since it is analog, it is a very reliable solution for measuring resistance or voltage output. It is also very economical compared to digital potentiometers, as it doesn\'t require additional encoding chips. Moreover, it is easy to use and can be easily integrated into various circuits. This component is also useful in creating PWM (Pulse Width Modulation) regulated control loops.

In Summary

The SPPG048S102U is a single-turn rotary IC potentiometer specifically designed to measure resistance or voltage levels. It utilizes a physical property of electrical resistance, where a low value resistor placed between two terminals of the unit changes its resistance when the knob is rotated. This IC has a wide range of applications in automotive, medical, consumer and general-purpose applications. It is also easy to use and is economical compared to digital potentiometers.
