1 / 14 page Semiconductor Components Industries, LLC, 2013 July, 2013 − Rev. 3 1 Publication Order Number: CAT5271/D CAT5271, CAT5273 Dual 256‐position I2C Compatible Digital Potentiometers (POTs) The CAT5271 and CAT5273 are dual 256-position digital programmable linear taper potentiometers 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 devices can be programmed to go to a shutdown state during operation. The CAT5271 and CAT5273 operate 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 them ideal for battery-powered portable applications. The CAT5271 and CAT5273, designed as pin for pin replacements for the AD5243 and AD5248, are offered in the 10-lead MSOP package and operate over the −40C to +85C industrial temperature range.
