General Description
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 0.1A.
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.
The MAX5450–MAX5455 are ideal for applications
requiring digitally-controlled resistors. Three resistance
values are available: 10k
, 50k, and 100k. 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
The MAX5450–MAX5455 are available in 10-pin MAX
and 14-pin TSSOP packages. Each device is guaran-
teed over the extended–industrial temperature range
(-40°C to +85°C).
