For an upgraded version with enhanced performance, please refer to LMV321A, LMV358A, and LMV324A.
The LMV321, LMV358, and LMV324 devices are single, dual, and quad low-voltage (2.7 V to 5.5 V) operational amplifiers with rail-to-rail output swing. These devices are the most cost-effective solutions for applications where low-voltage operation, space saving, and low cost are needed. These amplifiers are designed specifically for low-voltage (2.7 V to 5 V) operation, with performance specifications meeting or exceeding the LM358 and LM324 devices that operate from 5 V to 30 V. With package sizes down to one-half the size of the DBV (SOT-23) package, these devices can be used for a variety of applications.

CIRCUIT060013 — 具有 T 網路回饋電路的反相放大器
此設計可反轉輸入訊號 VIN，並使用 1000 V/V 或 60 dB 訊號增益。具有 T 回饋網路的反相放大器可在沒有較小 R4 值或超大回饋電阻器值的情況下獲得高增益。

CIRCUIT060074 — 具有比較器電路的高壓側電流感測
此高壓側電流感測解決方案使用一個具有軌對軌輸入共模範圍的比較器，若負載電流上升到 1 A 以上，便在比較器輸出 (COMP OUT) 建立過電流警示 (OC 警示) 訊號。此實作中的 OC 訊號為低電位作動。因此當超過 1-A 閾值時，比較器輸出會變低。實作磁滯後會在負載電流降低至 0.5 A (減少 50%) 時，讓 OC-Alert 返回邏輯高狀態。此電路利用開漏輸出比較器，為控制數位邏輯輸入針腳而進行電平轉換輸出高邏輯電平。對於需要驅動 MOSFET 開關閘極的應用，建議使用具推挽輸出的比較器。
