DescriptionThe AD5162 provides a compact 3 mm*4.9 mm packaged solution for dual 256-position adjustment applications.This device performs the sanme electronic adjustment function as a3-terminal mechanical potentiometer.Available in four different end-to-endresistance values(2.5k,10k,50k,100k),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 wither endpoint of the fixed resistor varies linearly with respect to the digital code transferred the RDAC latch.
Operating from a 2.7V to 5.5V power supply and consumung less than 6A allows the AD5162 to be used in portable battery-operated applications
For applications that program the ad5612 at the factory,analog devices offers device programming software running on windows nt/2000/xp operating systems.This software effectively replaces any external SPI controllers, which in turn enhances users'systems time-to-market. An AD5162 evaluationkit and software are available. The kit includes a cable and instruction manual.
