Texas Instruments LPV801/LPV802 Nanopowerオペレーショナルアンプ

Texas Instruments LPV801/LPV802 Nanopowerオペレーショナルアンプは、超低消費電力のオペアンプで、バッテリ駆動のワイヤレス、および低消費電力の有線機器によるセンシング用途向けです。LPV80xアンプは、CO検出器、煙検出器、PIRモーション検出器など、バッテリ駆動時間が重要な機器において消費電力を最小化できます。LPV80は、320nAの静止電流で8kHzの帯域幅を実現します。

These Texas Instruments LPV80x amplifiers have CMOS input stages with typically femtoamp bias currents and feature a negative-rail sensing input stage and a rail-to-rail output stage. This stage is capable of swinging within millivolts of the rails, maintaining the widest dynamic range possible. EMI protection is designed into the LPV80x to reduce system sensitivity to unwanted RF signals from mobile phones, Wi-Fi, radio transmitters, and tag readers.
