AD5247BKSZ5-RL7

AD5247 is a 128-position I²C-compatible digital potentiometer. This device performs the same electronic adjustment function as a mechanical potentiometer or a variable resistor. The wiper settings are controllable through the I²C-compatible digital interface, which can also be used to read back the present wiper register control word. The resistance between the wiper and either end point of the fixed resistor varies linearly with respect to the digital code transferred into the RDAC latch. It is widely used in application such as mechanical potentiometer replacement in new designs, transducer adjustment of pressure, temperature, position, chemical, and optical sensors, RF amplifier-biasing, LCD brightness and contrast adjustment, automotive electronics adjustment, gain control and offset adjustment etc.
