ADI AD5162BRMZ2.5-RL7

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 end - to - end resistance values (2.5 kΩ, 10 kΩ, 50 kΩ, 100 kΩ), 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 either endpoint 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 6 μA allows the AD5162 to be used in portable battery - operated applications.

For applications that program the AD5162 at the factory, Analog Devices offers device programming software running on Windows NT/2000/XP operating systems. This software effectively replaces the need for external SPI controllers, which in turn enhances the time to market of systems. An AD5162 evaluation kit and software are available. The kit includes a cable and instruction manual.
