CAT5271

Dual 256-Position I²C

Compatible Digital

Potentiometer

The CAT5271 is a dual 256−position digitally programmable linear

taper potentiometer ideally suited for replacing mechanical

potentiometers and variable resistors.

The wiper settings are controlled through an I C−compatible digital

interface. Upon power−up, the wiper assumes a midscale position and

may be repositioned anytime after the power is stable. The device can

be programmed to go to a shutdown state during operation.

The CAT5271 operates from 2.7 V to 5.5 V, while consuming less

than 2 mA. This low operating current, combined with a small package

footprint, makes the CAT5271 ideal for battery−powered portable

applications.

CASE 846AE

The CAT5271, designed as a pin for pin replacement for the

AD5243, is offered in the 10−lead MSOP package and operates over

the −40°C to +85°C industrial temperature range.
