These parts are ideal for applications requiring digitally controlled resistors. Three resistance values are available for each part type: 50k, 100k, and 200k. 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-temperature-coefficient variable resistor, such as low-tempco, adjustable-gain circuit configurations. The MAX5160 is available in an 8-pin MAX package, and the MAX5161 is available in a 6-pin SOT23 package. Both devices are guaranteed over the extendedindustrial temperature range (-40C to +85C).
