产品信息

The CAT5271 is a dual 256-positionlinear taper digital POT 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 µA. This low operating current, combined with a small package footprint, makes the CAT5273 ideal for battery-powered portable applications.
The CAT5271, designed as a pin for pin replacement for the AD5248, operates over the -40°C to +85°C industrial temperature range.
