概览

LMV321/NCV321、LMV358 和 LMV324 是带有轨对轨输出摆幅的单路、双路和四路低电压运算放大器。此类成本高效的放大器方案适用于低功耗和节省空间封装至关重要的应用。针对 2.7 V 和 5 V 电源电压运行提供规格表。轨对轨运行可实现优化的信噪比应用。超低静止电流使得此系列放大器适用于便携式电池供电设备。共模输入范围包括接地，使得此器件适用于低压侧电流分路测量。超小封装允许其放置在靠近信号源的 PCB 上，因此减少了噪声拾取。

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.)
