概览

CAT5261 是两数字 POT，集成了控制逻辑和 8 字节的 NVRAM 内存。每个数字 POT 由一系列电阻元件组成，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 8 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 8 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 SPI 串行总线写入弧刷控制寄存器或任何非易失性数据寄存器。加电时，每个电位计的第一个数据寄存器 (DR0) 的内容会自动加载到其各自的弧刷控制寄存器中。CAT5261 可用作电位计或两端可变电阻器。它适用于各种应用中的电路电平或系统电平调整。它可以在 -40°C 到 85°C 的工业运行温度范围内使用。

Re-calculate Data

Data is based on the following assumptions.

Note: The temperature and confidence level may be adjusted to your requirements.

Disclaimer: A reliability FIT rate calculated using this tool shall not be used for any functional safety purpose. In case a raw FIT rate needs to be estimated for a component which is targeted to be used in a safety critical application (i.e. compliant to ISO 26262 standard) it should be calculated according to generic safety standards (IEC62380, IEC61709, SN29500, FIDES, etc.)
