GENERAL DESCRIPTION

The AD5243 and AD5248 provide a compact 3 mm × 4.9 mm

packaged solution for dual 256-position adjustment applica-

tions. These devices perform the same electronic adjustment

function as a 3-terminal mechanical potentiometer (AD5243)

or a 2-terminal variable resistor (AD5248). Available in four

different end-to-end resistance values (2.5 kΩ, 10 kΩ, 50 kΩ,

and 100 kΩ), these low temperature coefficient devices are ideal

for high accuracy and stability variable resistance adjustments.

The wiper settings are controllable through the I²C compatible

digital interface. The AD5248 has extra package address decode

pins AD0 and AD1, allowing multiple parts to share the same

I²C 2-wire bus on a PCB. 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 for usage in portable battery-operated

applications.

For applications that program the AD5243/AD5258 at the

factory, Analog Devices offers device programming software

running on Windows® NT/2000/XP operating systems. This

software effectively replaces any external I²C controllers, which

in turn enhances users’ systems time-to-market. An AD5243/

AD5248 evaluation kit and software are available. The kit

includes a cable and instruction manual.

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