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.
