DS1841

温度控制、NV、I²C对数电阻器

DS1841一款7位对数变化的非易失(NV)数字电位器,内置温度传感器和对应的模/数转换器(ADC)。集成温度传感器带有一个72字节的NV查找表(LUT),覆盖温度范围-40°C至+100°C。LUT输出能够直接驱动电阻,或添加到NV初始值寄存器(IVR)内,用于驱动电阻。这种基于LUT的灵活架构使得DS1841能够以任意斜率提供温度补偿电阻输出。该器件通过I²C兼容接口编程,接口工作速率高达400kHz。 • 22kΩ至3.7kΩ对数抽头可调电阻,具有3.6kΩ固定电阻 \n• 128个抽头位置 \n• 片上温度传感器和ADC \n• 72字节查找表(LUT) \n• I²C兼容串行接口 \n• 地址引脚允许多达4个DS1841共用一条I²C总线 \n• 数字电路供电电压为2.7V至5.5V \n• 工作温度范围:-40°C至+100°C \n• 3mm x 3mm、10引脚TDFN封装;
