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 conve-  
nient power-on reset (POR) sets the wiper to midscale  
position at power-up and the easy-to-use up/down  
interface allows glitchless switching between  
resistor taps. Six inputs control the 14-pin MAX5451/  
MAX5453/MAX5455 potentiometers. Four inputs control  
the 10-pin MAX5450/MAX5452/MAX5454 variable resis-  
tors.

(Position 127)  
ꢀ Glitchless Switching Between the Resistor Taps  
ꢀ 10kΩ, 50kΩ, 100kΩ Resistance Values  
The MAX5450–MAX5455 are ideal for applications  
requiring digitally-controlled resistors. Three resistance  
values are available: 10kΩ, 50kΩ, and 100kΩ. An end-  
to-end resistor temperature coefficient of 35ppm/°C  
and a ratiometric temperature coefficient of 5ppm/°C  
make the MAX5450–MAX5455 excellent choices for  
adjustable gain circuit requiring low-temperature drift
