The MAX5401EKA+T is an integrated circuit (IC) component manufactured by Maxim Integrated. It is a digital potentiometer with a 256-tap resolution and a ±1% linearity over its entire resistance range. This IC is designed to replace mechanical potentiometers in various applications.
One of the key features of the MAX5401EKA+T is its 256-tap resolution, allowing for fine adjustments in the resistance value. It can operate as a three-terminal potentiometer or as a two-terminal rheostat. This flexibility makes it suitable for use in a wide range of applications, including audio systems, voltage references, test equipment, and industrial automation.
The IC operates from a single 2.7V to 5.25V power supply and consumes low power, making it energy-efficient. Furthermore, it incorporates a non-volatile memory that stores the wipers' position during power-off, ensuring that the potentiometer retains its settings.
The MAX5401EKA+T features an I²C-compatible serial interface, enabling easy connectivity with microcontrollers and other digital devices. This digital interface allows for simple control and adjustment of the resistance value, facilitating accurate and precise adjustments in the system.
The IC also provides additional functionality, such as the ability to provide a shutdown mode. This feature allows for reduced power consumption when the device is not in use, making it suitable for power-sensitive applications
