CAT5172 是一款 256 位线性锥化数字 POT,适用于替代机械电位计和可变电阻。与机械电位计一样,CAT5172 具有电阻元件,可跨越 VCC 到接地,或者在电源轨之间的任何位置浮动。弧刷设置通过可兼容 SPI 的数字接口进行控制。通电后,弧刷采用中间范围位置,可在电源稳定之后任何时间重新定位。CAT5172 运行电压为 2.7 V 至 5.5 V,消耗电流不到 2 µA。这种低运行电流,结合小封装占位,使得 CAT5172 适用于电池供电的便携式设备。

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.)
