The LMV61x devices are single, dual, and quad low-voltage, low-power operational amplifiers (op amps). They are designed specifically for low-voltage, general-purpose applications. Other important product characteristics are, rail-to-rail input or output, low supply voltage of 1.8 V and wide temperature range. The LMV61x input common mode extends
200 mV beyond the supplies and the output can swing rail-to-rail unloaded and within 30 mV with 2-kΩ load at 1.8-V supply. The LMV61x achieves a gain bandwidth of 1.4 MHz while drawing 100-µA (typical) quiescent current.

The industrial-plus temperature range of −40°C to 125°C allows the LMV61x to accommodate a broad range of extended environment applications.

The LMV611 is offered in the tiny 5-pin SC70 package, the LMV612 in space-saving 8-pin VSSOP and SOIC packages, and the LMV614 in 14-pin TSSOP and SOIC packages. These small package amplifiers offer an ideal solution for applications requiring minimum PCB footprint. Applications with area constrained PCB requirements include portable and battery-operated electronics.

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。
