MAX5482ETE+

The MAX5482ETE+ from Maxim Integrated Products is a 10bit, non-volatile, linear taper digital potentiometer in 16 pin TQFN package. This programmable 3-terminal voltage divider performs the function of a mechanical potentiometer but replace the mechanics with a pin configurable 3-wire serial SPI™-compatible interface or up/down digital interface. It features an internal, non-volatile, EEPROM that stores wiper position for initialization during power up. It is ideal for applications requiring digitally controlled potentiometers. The nominal resistor temperature coefficient is 35ppm/°C end to end and only 5ppm/°C ratiometric making it ideal for applications requiring low-temperature-coefficient voltage dividers such as low-drift, programmable gain-amplifiers. Typical applications include gain and offset adjustment, LCD contrast adjustment, pressure sensors, low-drift programmable gain amplifiers and mechanical potentiometer replacement.
