AD5161BRMZ5

AD5161 is a 256-position SPI/I²C selectable digital potentiometer. It perform the same electronic adjustment function as mechanical potentiometers or variable resistors, with enhanced resolution, solid-state reliability, and superior low temperature coefficient performance. The wiper settings are controllable through a pin selectable SPI or I²C compatible digital interface, which can also be used to read back the wiper register content. When the SPI mode is used, the device can be daisy-chained (SDO to SDI), allowing several parts to share the same control lines. In the I²C mode, address pin AD0 can be used to place upto two devices on the same bus. It is widely used in application such mechanical potentiometer replacement in new designs, transducer adjustment of pressure, temperature, position, chemical, and optical sensors, RF amplifier biasing, gain control and offset adjustment etc.
