Data Acquisition - Digital Potentiometers

Digital potentiometers are used as variable resistors, or volume controls in many types of electronic circuits. Their primary application is in the implementation of data acquisition systems, which require precise and stable control of resistance values. The AD5247BKSZ100-1RL7 is one such digital potentiometer specifically designed for data acquisition systems.

Application Field

The AD5247BKSZ100-1RL7 is a ultra-high precision, low voltage, non-volatile digital potentiometer. It has many applications in both industrial and consumer electronics. It is used for motor and loudspeaker control, automatic volume control, and a range of inverter circuits for power supply regulation. It can also be used for data acquisition systems that require precise and stable control of resistance values.

Working Principle

The AD5247BKSZ100-1RL7 is an electromechanical device which works by changing the resistance of the resistive element between the two terminals in response to a control input. It consists of two parts: the mechanical element, which is the physical switched resistor, and the electronic control circuit, which is responsible for controlling the resistance.

The electronic control circuit is composed of a digital switch, which is responsible for controlling the resistance value. An external control signal is applied to the switch, causing it to change the resistance value appropriately. This control signal can be either a digital value, or an analog voltage.

The mechanical element consists of various resistor elements with various resistance values. The digital switch control which resistive element is selected and thus determines the total resistance value between the two terminals.

The AD5247BKSZ100-1RL7 is capable of accurately controlling the resistance between the two terminals with a resolution of 0.1%. It is also very stable, with a temperature coefficient of 0.1%/°C, making it very suitable for data acquisition systems that require precise and stable control of resistance values.
