AD5110BCPZ80-1-RL7

AD5110BCPZ80-1-RL7 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 new low wiper resistance feature minimizes the wiper resistance in the extremes of the resistor array to only 45ohm, typical. The wiper settings are controllable through an I²C-compatible digital interface that is also used to readback the wiper register and EEPROM content. 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.
