Description

The AD5160 provides a compact 2.9 mm × 3 mm packaged solution for 256-position adjustment applications. These devices AD5160 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 an SPI compatible digital interface. 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.Operating from a 2.7 V to 5.5 V power supply and consuming less than 5 µA allows for usage in portable battery-operated applications.
