CAT5271 是一款双 256 位线性锥化数字 POT,适用于替代机械电位计和可变电阻。弧刷设置通过一个 I2C 兼容数字接口控制。通电时,弧刷采用中间量程位置,电源稳定后可随时调整位置。该器件可进行编程,在运行期间进入关断状态。CAT5271 的运行范围为 2.7 V 至 5.5 V,消耗电流小于 2 µA。这种低运行电流,结合小封装占位,使得 CAT5273 适用于电池供电的便携式应用。CAT5271 设计用作 AD5248 的引脚对引脚替代产品,基于 -40°C - +85°C 工业温度范围运行。

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.)
