Datasheet Maxim MAX5161LEZT+ — 数据表

19-1435; Rev 2a; 2/01 Low-Power Digital Potentiometers
Features
♦ 32 Tap Positions These parts are ideal for applications requiring digitally
controlled resistors. Three resistance values are available 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-temperature-coefficient variable resistor, such as low-tempco,
adjustable-gain circuit configurations. ♦ 3-Wire Serial Data Input The MAX5160 is available in an 8-pin µMAX package,
and the MAX5161 is available in a 6-pin SOT23 package. Both devices are guaranteed over the extendedindustrial temperature range (-40°C to +85°C). Applications
