AD5110 Single Channel, 128-Position, I2C, ±8% Resistor Tolerance, Nonvolatile Digital Potentiometer
The AD5110 provides a nonvolatile solution for 128-position adjustment applications, offering guaranteed low resistor tolerance errors of ±8% and up to ±6 mA current density in the A, B, and W pins. The low resistor tolerance, low nominal temperature coefficient and high bandwidth simplify open-loop applications, as well as tolerance matching applications.
The new low wiper resistance feature minimizes the wiper resistance in the extremes of the resistor array to only 45 Ω,
typical.
The wiper settings are controllable through an I2C-compatible digital interface that is also used to readback the wiper register and EEPROM content. Resistor tolerance is stored within EEPROM, providing an end-to-end tolerance accuracy of 0.1%.
The AD5110 is available in a 2 mm × 2 mm LFCSP package. The parts are guaranteed to operate over the extended industrial temperature range of −40°C to +125°C.
