CAT5271

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. 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.
