CAT5241 是四数字 POT,集成了控制逻辑和 16 字节的 NVRAM 内存。每个数字 POT 由一组 63 个电阻元件组成,这些电阻元件联接在两个外部可访问的端点之间。每个电阻元件之间的抽头点通过 CMOS 开关连接到弧刷输出。一个单独的 6 位控制寄存器 (WCR) 独立控制每个数字 POT 的弧刷抽头开关。与每个弧刷控制寄存器相关联的是四个 6 位非易失性内存数据寄存器 (DR),用于存储最多四个弧刷设置。通过 2 线串行总线(类似 I²C)写入弧刷控制寄存器或任何非易失性数据寄存器。通电时,四个电位计中的每个电位计的第一个数据寄存器 (DR0) 的内容自动加载到各自的弧刷控制寄存器 (WCR) 中。CAT5241 可以用作电位计或两端子可变电阻。它适用于各种应用中的电路电平或系统电平调整。
