GENERAL OVERVIEW
The AD5160 provides a compact 2.9 mm × 3 mm packaged
solution for 256-position adjustment applications. These devices
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.
