Evaluation and Demonstration Boards and Kits

The EVAL-AD5252EBZ is a board and kit from Analog Device Incorporated. It is part of their evaluation module product line which allows engineers to evaluate and demonstrate Analog Device Incorporated\'s products and their functionality. This evaluation board and kit is designed to evaluate the functionality of the AD5252 Digital Potentiometer IC.

Application Field

The EVAL-AD5252EBZ is designed to test, evaluate, and demonstrate the features and functions of the AD5252 Digital Potentiometer IC. It is intended for use in applications that require variable resistor functionality. This could include implementing adjustable gain, level shifting, and adjustable filtering in audio, automotive, and industrial systems.

Working Principle

The AD5252 has an 8-bit resolution and a 256-position count register. It uses a precision control system to control precise resistance settings. The value of the output resistor is set by the device\'s serial input. This serial input is routed to the device via SDA/SCL lines that communicate with the I2C protocol. Additionally, the EVAL-AD5252EBZ board contains an RT and a RR terminal cell that allows for further resistance changes. The RT terminal represents the output resistance terminal and the RR terminal represents the terminal cell\'s return resistance. The changes in the output resistance are tied to the changes in the RT and RR terminals.

The EVAL-AD5252EBZ board also contains a power supply section that can be switched between a 3V and a 5V DC source. It also contains an LED indicator to signal the device\'s output status through its I2C communication. Other features such as a jumpers and test points offer further adjustability.
