series introduction

# AD5282BRU200 Product Series Introduction

## 1. Overview
The AD5282BRU200 is a remarkable product series offered by Analog Devices, a leading name in the semiconductor industry. This series belongs to the category of digital potentiometers, which are electronic components that provide a variable resistance similar to traditional mechanical potentiometers but with the added benefits of digital control. The AD5282BRU200 is designed to meet the diverse needs of modern electronic systems, offering high precision, reliability, and flexibility.

## 2. Key Features

### 2.1 High - Resolution Digital Control
The AD5282BRU200 features a high - resolution digital interface. It typically offers a large number of wiper positions, allowing for fine - grained adjustment of the resistance value. This high resolution enables precise control in applications where accurate resistance settings are crucial, such as in audio volume control, sensor calibration, and power supply regulation.

### 2.2 Low Temperature Coefficient
One of the significant advantages of this product series is its low temperature coefficient. Temperature variations can cause the resistance of a potentiometer to change, which may lead to inaccuracies in the system. The AD5282BRU200 is engineered to minimize this effect, ensuring stable performance over a wide temperature range. This makes it suitable for use in harsh environments where temperature fluctuations are common.

### 2.3 Non - Volatile Memory
The AD5282BRU200 is equipped with non - volatile memory. This means that the last set resistance value is retained even when the power is removed. When the device is powered on again, it automatically restores the previously set resistance, eliminating the need for re - calibration and providing convenience in system operation.

### 2.4 I²C Interface
It utilizes an I²C (Inter - Integrated Circuit) interface for communication. The I²C interface is a widely used serial communication protocol that offers simplicity, low pin count, and the ability to connect multiple devices on the same bus. This makes it easy to integrate the AD5282BRU200 into existing electronic systems, reducing the complexity of the overall design.

### 2.5 Low Power Consumption
In today's energy - conscious world, low power consumption is a highly desirable feature. The AD5282BRU200 is designed to operate with minimal power requirements, making it suitable for battery - powered devices and other applications where power efficiency is a priority.

## 3. Technical Specifications

### 3.1 Resistance Range
The AD5282BRU200 offers a specific resistance range. For example, it may have a total resistance of 200 kΩ, which can be adjusted in discrete steps using the digital control interface. This resistance range provides a wide scope for different applications, allowing designers to select the appropriate resistance value for their specific needs.

### 3.2 Wiper Resolution
The wiper resolution determines the number of discrete steps in which the resistance can be adjusted. The AD5282BRU200 typically has a high wiper resolution, such as 256 steps. This high resolution enables precise control of the resistance, making it suitable for applications that require accurate voltage division or impedance matching.

### 3.3 Supply Voltage Range
It can operate within a certain supply voltage range. For instance, it may support a supply voltage from 2.7 V to 5.5 V. This wide supply voltage range provides flexibility in powering the device, allowing it to be used in a variety of electronic systems with different power requirements.

### 3.4 Operating Temperature Range
The AD5282BRU200 is designed to operate over a wide temperature range,
