GENERAL DESCRIPTION

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.¹

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.

¹The terms digital potentiometer, VR, and RDAC are used interchangeably.
