数字电位计 (POT),256 抽头,带 I2C 接口和集成的 EEPROM

Favorite

概览

CAT5140 是一款单沟道非易失性 256 抽头数字 POT。此数字 POT 由一组在两个外部可访问端点之间联接的等值电阻元件组成。每个电阻元件之间的抽头点可以选择通过内部 CMOS 开关联接更宽的输出,组成一个线性抽头电子电位计。CAT5140 包括一个易失性孤刷寄存器 (WR) 和一个用于孤刷位置的 8 位非易失性 EEPROM,以及 5 非附加的非易失性寄存器组成,用于通用数据存储。这些寄存器的编程通过 I2C 接口控制。通电时,孤刷位置将重置为非易失性内存寄存器 (IVR) 存储的最新值。CAT5140 基于 -40°C 至 +85°C 的工业温度范围运行。
