R(ab): 2.5 kOhm; V(dd): -0.3 to +7V; +-20mA; dual 256-position SPI digital potentiometer. For system calibrations, electronic level settings, mechanical trimmers replacement in new designs, permanent factory PCB setting, etc.
The AD5162 provides a compact 3 mm x 4.9 mm packaged solution for dual 256-position adjustment applications. This device performs the same electronic adjustment function as a 3-terminal mechanical potentiometer. Available in four different end-to-end resistance values (2.5 k, 10 k, 50 k, 100 k), this low temperature coefficient device is ideal for high accuracy and stability variable resistance adjustments. The wiper settings are controllable through an SPI digital interface. The resistance between the wiper and either endpoint of the fixed resistor varies linearly with respect to the digital code transferred into the RDAC1 latch.
