DS1855

双路、非易失数字电位器及安全存储器

DS1855双路非易失性(NV)数字电位器和安全存储器由一个100级线性变化电位器、一个256级线性变化电阻器、256字节EEPROM存贮器、和2线接口组成。DS1855具有软件写保护,是DS1845的升级产品。DS1855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。EEPROM存储器允许用户存储用于某个特定系统或设备的配置或校准数据,以及提供控制电阻器抽头设置。任何类型的用户信息可以保存在存储器的前248个字节中。接下来的2个EEPROM地址用于存储电位器设置,剩下的6个字节为保留字。这些保留字和电位器寄存器不能用于数据存储。通过工业标准2线总线访问该EEPROM。I • 两个线性变化电阻器 \n• DS1855-010 (一个10kΩ、100级和一个10kΩ、256级) \n• DS1855-020 (一个10kΩ、100级和一个20kΩ、256级) \n• DS1855-050 (一个10kΩ、100级和一个50kΩ、256级) \n• DS1855-100 (一个10kΩ、100级和一个100kΩ、256级) \n• 256字节的EEPROM存储器 \n• 通过2线接口,实现数据存储和电位器控制 \n• 外部写保护引脚保护数据和电位器设置 \n• 也可以通过软件控制提供数据和电位器设置写保护 \n• 非易失性抽头位置存储 \n• 工作电源电压3V或5V;
