The LMV821/LMV822/LMV824 op amps bring performance and economy to low voltage, low power systems. With a 5 MHz unity-gain frequency, at 2.7 V supply, and a 1.4 V/µs slew rate, the quiescent current is only 220 µA per amplifier. They provide rail to rail output (RRO) swing into 600 Ω load. The input common-mode voltage range includes ground and the maximum input offset voltage is 3.5 mV. They are also capable of easily driving large capacitive loads as indicated in the applications section.

The LMV821 single op amp is available in the tiny SC70-5 package, which is about half the size of the previous title holder, the SOT23-5. The LMV824NDGV is specified over the extended industrial temperature range and is in a TVSOP package.

Overall, the LMV821/LMV822/LMV824 devices are low voltage, low power and performance op amps designed for a wide range of applications at an economical price.

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。
