概览

NCS325 是一款 CMOS 运算放大器，提供精确性能。零漂移结构可实现连续自动校正，提供极低的偏移、随时间和温度的近零漂移，还提供接近水平的 1/f 噪声，静止电流仅为 35 µA（最大）。这些优点使其适用于精确直流应用。NCS325 提供轨对轨输入和输出性能，适合在最低 1.8 V 和最高 5.5 V 的低电压下运行。NCS325 采用节省空间的 SOT23−5 封装。

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.)
