DS1847：双路、温控、非易失可变电阻
DS1847双路温控非易失性(NV)可变电阻器由两个256级线性可变电阻器组成。DS1847-050由一个10kΩ和一个50kΩ电阻组成，DS1847-010由两个10kΩ电阻组成；两种都包括一个数字式温度传感器。该器件尤其适用于控制应用中设定和温度补偿偏置电压和电流，且只需最少的电路。 可变电阻器的设置存储在EEPROM存储器中，并可通过工业标准的2线串行总线进行存取。每个可变电阻器的数值由温度寻址的查询表决定，在整个-40°C至+95°C温度范围内，以2°C间隔给每个电阻分配一个数值。通过串行总线，数字温度传感器输出13位、二进制补码的温度值。接口I/O引脚由SDA和SCL组成。
