GENERAL OVERVIEW
The AD5290 is a low cost, compact 2.9 mm × 3 mm
+30V/±15V, 256-position digital potentiometer. This device
performs 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.
The AD5290 is available in 10k, 50k, and 100k
in compact
MSOP-10 package. AD5290 can be operated from a single
supply +2.7 V to +30 V or dual supply ±2.7 V to ±15 V. All
parts are guaranteed to operate over the automotive
temperature range of -40°C to +105°C.
