MAX5478EUD Description

Short technical summary and product information.

The MAX5478EUD is a dual-channel digital potentiometer manufactured by Analog Devices, designed for precise resistance control in electronic circuits. This device offers 256 taps per channel, providing fine-grained adjustment capabilities. It features a linear taper and a non-volatile memory, allowing settings to be retained even after power loss.

 

The digital potentiometer operates via an I2C interface, enabling easy integration into microcontroller-based systems. It supports a wide operating voltage range from 2.7V to 5.25V and functions across a temperature range of -40°C to 85°C. The MAX5478EUD is available in a 14-TSSOP surface-mount package, making it suitable for compact designs.

 

Key electrical characteristics include a resistance value of 62.5k Ohms and a typical temperature coefficient of 70ppm/°C. The selectable address feature adds flexibility in systems with multiple devices. This component is ideal for applications requiring adjustable voltage dividers, gain control, or filter tuning.
