AD5114BCPZ10-500R7

AD5114BCPZ10-500R7 is a single-channel, 128-position, I²C, 8% resistor tolerance, non-volatile digital potentiometer. The low resistor tolerance, low nominal temperature coefficient, and high bandwidth simplify open-loop applications, as well as tolerance matching applications. 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%. It is used in applications such as mechanical potentiometer replacement, portable electronics level adjustment, audio volume control, low-resolution DAC, LCD panel brightness and contrast control, programmable voltage to current conversion, programmable filters, delays, time constants, feedback resistor programmable power supply, sensor calibration.
