General Description
The MAX5402 μPoT
digital potentiometer is a 256-tap
variable resistor with 10k
total resistance in a tiny 8-
pin μMAX package. This device functions as a mechan-
ical potentiometer, consisting of a fixed resistor string
with a digitally controlled wiper contact. It operates
from +2.7V to +5.5V single-supply voltages and uses
an ultra-low 0.1μA supply current. This device also pro-
vides glitchless switching between resistor taps, as well
as a convenient power-on reset (POR) that sets the
wiper to the midscale position at power-up. A low
5ppm/°C ratiometric temperature coefficient makes it
ideal for applications requiring low drift.
The MAX5402 serves well in applications requiring digi-
tally controlled resistors, including adjustable voltage
references and programmable gain amplifiers (PGAs).
A nominal end-to-end resistor temperature coefficient of
35ppm/°C makes this part suitable for use as a variable
resistor in applications such as low-tempco adjustable
gain and other circuit configurations. This device is
guaranteed over the extended industrial temperature
range (-40°C to +85°C).
