The MAX5418LETA+T is a non-volatile linear taper digital potentiometer in 8 pin TDFN package. The device combines a single 256 position potentiometer and the control is achieved through I2C interface. It has an internal non-volatile EEPROM to store the wiper position for initialization during power-up. It minimizes board space and reduce interconnection complexity in many applications and are ideally suitable for low-drift, programmable gain amplifier circuit configurations.
Supply voltage range is 2.7V to 5.25V
Operating temperature range from -40°C to 85°C
Power-on recall of wiper position from non-volatile memory
Data rate is 400Kbps
Address input for eight unique address combinations
Ratiometric temperature coefficient of 5ppm/°C
Static supply current of 500nA
End to end resistance is 100Kohm and temperature coefficient is 35ppm/°C
