Data Acquisition – Digital Potentiometers refers to the set of techniques used to measure and analyze the current, voltage, temperature, time and frequency characteristics of a physical system. The technology includes both hardware and software in order to measure and analyze these characteristics. Digital Potentiometers are analog integrated circuits that can measure continuously varying analog signals without digital conversion. They are used to measure electrical signals such as voltage and current. These signals can then be analyzed and compared to other signals.
MCP4261-103E/ST is one type of digital potentiometers used for data acquisition. It is a Microchip Technology potentiometer that provides low voltage and low current analog-to-digital conversion. It is available in 4, 5, or 6 bit versions and integrated with a variety of input and output levels. It contains a 10K, 100K, 500K, and 1M ohm resistance ladder connected to a standard 10-bit dual slope ADC in order to maintain the output voltage range across various applications. It also provides 128 position settings that allow the user to easily adjust the resistance to their desired level. It is capable of converting analog signals from 0 to 20V with a resolution of better than 10mV. It also has a temperature operating range of 0-85°C, a supply voltage range of 2-5V, and a current consumption of 10mA.
The working principle of the MCP4261-103E/ST digital potentiometer is based on two basic concepts: resistive divider network and analog-to-digital conversion. The resistive divider network is designed to provide a specific resistance between the two supply power lines and the reference voltage line. In the MCP4261-103E/ST, the resistive divider network contains four resistors that provide four different resistance settings of 10K, 100K, 500K, and 1M ohms. The analog-to-digital converter is used to obtain the output voltage range by converting the analog signal into a digital value. The output voltage range is then displayed on the LCD or is used to drive the motor. The MCP4261-103E/ST provides four position settings, which allow the user to easily adjust the resistance to their desired level.
The MCP4261-103E/ST digital potentiometer is mainly used for industrial applications such as motor control, digital control systems, and motion control systems. This potentiometer is also used for audio applications such as amplifiers and audio signal processing gear. Other potential applications include automotive power controls, as well as medical devices and test equipment.
In summary, the MCP4261-103E/ST is a digital potentiometer used for data acquisition. It is integrated with a 10K, 100K, 500K, and 1M ohm resistance ladder for providing 128 position settings. It can be used for a wide range of industrial and audio applications, including motor control, digital control systems, audio amplifiers and signal processing, automotive power controls, medical devices, and test equipment. The working principle of the MCP4261-103E/ST is based on the resistive divider network and analog-to-digital conversion.
