CAT5271
Dual 256-Position I2C
Compatible Digital
Potentiometer
The CAT5271 is a dual 256âposition digitally programmable linear
taper potentiometer ideally suited for replacing mechanical
potentiometers and variable resistors.
The wiper settings are controlled through an I2Câcompatible digital
interface. Upon powerâup, 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 batteryâpowered portable
applications.
The CAT5271, designed as a pin for pin replacement for the
AD5243, is offered in the 10âlead MSOP package and operates over
the â40°C to +85°C industrial temperature range.
