The MAX5478ETE+ is a nonvolatile, dual, linear-taper digital potentiometer designed by Analog Devices. It functions as a mechanical potentiometer but utilizes a simple 2-wire digital interface, specifically an I2C-compatible serial interface operating at up to 400kbps. This device provides 256 tap points for precise control.
Key electrical specifications include a nominal resistance of 50kΩ with a ±25% tolerance. It operates over a wide voltage range of 2.7V to 5.25V and features a low static supply current of 1µA maximum. The temperature coefficient is 70ppm/°C end-to-end and 10ppm/°C ratiometric, making it suitable for applications requiring low drift.
This digital potentiometer includes an internal nonvolatile EEPROM to store the wiper position, ensuring power-on recall. A write-protect feature prevents accidental EEPROM overwrites. The device is available in a compact 16-pin TQFN package measuring 3mm x 3mm x 0.8mm, with a 16-WFQFN exposed pad. It operates within an extended temperature range of -40°C to +85°C.
Applications for the MAX5478ETE+ include mechanical potentiometer replacement, low-drift programmable-gain amplifiers, volume control, and liquid-crystal display (LCD) contrast control.
