Data Acquisition - Digital PotentiometersDigital potentiometers are electronic devices that can be used to vary the amount of resistance, voltage or current in a given circuit. The AD8403ARU100 is an 8-bit digitally adjustable resistor, which is a type of digital potentiometer. It is a single-supply, 16-pin device, capable of sourcing and sinking up to 20 mA.The AD8403ARU100 is designed for applications that require small size and low power consumption, such as automotive, consumer, industrial and communication systems. It can be used in various types of data conversion, signal conditioning and signal routing. The device can also be used for filtering applications, such as audio, power management and voltage regulation.The AD8403ARU100’s working principle is based on the concept of digitally adjustable resistor, where a resistance change occurs in response to a digital input. The lower 8 bits (LSB) of the product code is used to configure the resistance value. The value of each LSB is determined by a resistor ratio (R1/R2) and a tap-on/tap-off value. When the tap is on, the resistance value is increased and when the tap is off, the resistance value is decreased.The AD8403ARU100 offers a wide range of resistances, covering values up to 100 kΩ. Its low power consumption and small size make it suitable for a wide range of applications and data acquisition with high accuracy and resolution. Its versatile output mode allows for the use of two sets of outputs for different functions and flexibility.In addition, the AD8403ARU100 is designed to allow for flexibility in its operation. It is capable of operating in a variety of modes, such as differential, open loop and switched mode. This allows for flexibility in applications such as level shifting and gain scaling.The AD8403ARU100 is a versatile device with a wide range of uses. Its small size, low power consumption and high accuracy make it suitable for many applications. From data conversion and signal conditioning, to filtering and audio applications, the AD8403ARU100 is a valuable tool for a variety of application fields.
