The MAX5160/MAX5161 linear-taper digital potentiome-
ters perform the same function as a mechanical poten-
tiometer or a variable resistor. They consist of a fixed
resistor and a wiper contact with 32 tap points that are
digitally controlled by three lines for the 8-pin MAX5160
or by two lines for the 6-pin MAX5161.
These parts are ideal for applications requiring digitally
controlled resistors. Three resistance values are avail-
able for each part type: 50kΩ, 100kΩ, and 200kΩ. A
nominal resistor temperature coefficient of 50ppm/°C
end-to-end and only 5ppm/°C ratiometric makes the
MAX5160 ideal for applications requiring a low-temper-
ature-coefficient variable resistor, such as low-tempco,
adjustable-gain circuit configurations.
The MAX5160 is available in an 8-pin µMAX package,
and the MAX5161 is available in a 6-pin SOT23 pack-
age. Both devices are guaranteed over the extended-
industrial temperature range (-40°C to +85°C).
