I2C, 非易失性存储器、双通道、64位数字电位计

AD5251是一款具有64位的双通道、I2C、非易失性存储器、数控电位计。可实现与机械电位计、调整器和可变电阻相同的电子调整功能。器件的多功能编程能力支持多种工作模式，包括对RDAC和EEMEM寄存器进行读/写访问、电阻递增/递减、±6 dB电阻量程变化和游标设置回读，同时提供额外的EEMEM，用于存储用户定义信息，如其他元件的存储器数据、查找表或系统识别信息。\n\n AD5251/AD5252允许主I2C控制器在RDAC寄存器中写入64/256步游标设置并将其存储在EEMEM中。存储设置后，在系统上电时它们自动恢复到RDAC寄存器；也可动态恢复这些设置。\n\n AD5 • 双通道64位分辨率\n\n• 50 kΩ\n\n• 非易失性存储器存储带写入保护的游标设置 \n\n• 在300 µs（典型值）内上电刷新EEMEM设置\n\n• EEMEM重写时间 = 540 µs（典型值）\n\n• 电阻容差存储在非易失性存储器中\n\n• 在EEMEM中存储12个额外的字节，用于用户定义信息\n\n• I2C兼容串行接口\n\n• 对RDAC和EEMEM寄存器进行直接读/写访问\n\n• 预定义线性递增/递减命令\n\n• 预定义±6 dB步进变化命令\n\n• 同步或异步双通道更新\n\n• 游标设置回读功能\n\n• 4 MHz带宽——1 kΩ版本\n\n• 单;
