Overview

NCS325 は CMOS オペアンプで、高精度性能です。ゼロドリフト・アーキテクチャにより連続自動キャリブレーションが可能なので、超低オフセット、時間/温度範囲でほぼゼロドリフト、静止電流わずか 35 µA (最大) でほぼフラットな 1/f ノイズが実現します。こうしたメリットは高精度 DC アプリケーションに最適です。NCS325 にはレール・ツー・レール入出力性能があり、下は 1.8 V から上は 5.5 V までの低電圧動作に向けて最適化されています。NCS325 は省スペース SOT23−5 パッケージで提供されます。

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.)
