The AD5220BRM100 is an integrated circuit (IC) component designed by Analog Devices. It is a 128-position digital potentiometer with a non-volatile memory (NVM) and serial interface. This IC offers several key features that make it suitable for a wide range of applications.
One of the notable features of the AD5220BRM100 is its ability to replace mechanical potentiometers in various systems. It enables users to digitally control resistance, eliminating the need for manual adjustment. This electronic potentiometer provides a compact and reliable solution that can be easily integrated into circuits.
The IC has 128 resistive elements, which can be configured as a two-terminal variable resistor or a three-terminal potentiometer. With a resistance range of up to 100 kilohms, it can cater to different design requirements. The resolution of the AD5220BRM100 is 7 bits, allowing for precise adjustments.
Another important feature is the non-volatile memory (NVM) capability. This means that the IC can remember its resistance settings even when the power is disconnected. This feature is crucial in applications where the potentiometer needs to retain its value during power-offs or system restarts, ensuring consistent operation.
The AD5220BRM100 employs a serial interface, making it easy to connect with microcontrollers or other digital devices. It uses a standard I²C serial bus, which simplifies the interfacing process
