MAX5450–MAX5455
Dual, 256-Tap, Up/Down Interface, Digital Potentiometers
General Description
Features
The MAX5450–MAX5455 are a family of dual digital potentiometers that perform the same function as a mechanical potentiometer or variable resistor.
The MAX5451/MAX5453/MAX5455 have two 3-terminal potentiometers and the MAX5450/MAX5452/MAX5454 have two 2-terminal variable resistors.
The MAX5450– MAX5455 operate from a +2.
7V to +5.
5V single-supply
voltage and use an ultra-low supply current of 0.
1µA.
These devices consist of two fixed resistors each with 256 digitally-controlled wiper contacts.
The convenient power-on reset (POR) sets the wiper to midscale position at ...
