The AD8402ARUZ50-REEL is a highly versatile, digital potentiometer integrated circuit (IC) component, manufactured by Analog Devices. It is designed to offer precise digital adjustment of resistance, replacing traditional mechanical potentiometers.
Key features of the AD8402ARUZ50-REEL include a dual-channel configuration with 256 positions, enabling users to implement multiple levels of resistance. Each channel can be independently controlled via a 3-wire serial interface, providing digital-to-analog conversion capability. Moreover, the IC offers a wide operating voltage range of 2.7V to 5.5V, making it compatible with various applications.
This IC component integrates a resistor array, a wiper switch, and control logic, effectively creating a digitally controlled variable resistor. The built-in resistors are laser-trimmed for high accuracy, and the wiper switch enables the selection of different taps along the resistor array. Additionally, the AD8402ARUZ50-REEL provides low temperature coefficient performance for stable and reliable operation across varied environmental conditions.
One of the notable features is the ability to handle high levels of current, with a maximum current rating of 20mA. This makes it suitable for applications where precise control of resistance is required, such as in audio equipment, industrial control systems, and digital potentiometers
