GENERAL DESCRIPTION
The AD5162 provides a compact 3 mm × 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 d……
