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 I2C−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.
