The LMV116 (single) rail-to-rail output voltage feedback amplifiers offer high-speed (45 MHz), and low-voltage operation (2.7 V) in addition to micro-power shutdown capability (LMV118).

Output voltage range extends to within 20 mV of either supply rail, allowing wide dynamic range especially in low voltage applications. Even with low supply current of 600 µA, output current capability is kept at a respectable ±20 mA for driving heavier loads. Important device parameters such as BW, slew rate, and output current are kept relatively independent of the operating supply voltage by a combination of process enhancements and design architecture.

For portable applications, the LMV118 provides shutdown capability while keeping the turnoff current to 15 µA. Both turnon and turnoff characteristics are well behaved with minimal output fluctuations during transitions, thus the device can be used in power-saving mode, as well as multiplexing applications. Miniature packages (5-pin and 6-pin SOT-23) are further means to ease the adoption of these low-power, high-speed devices in applications where board area is at a premium.

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。
