The LM290xLV-Q1 family includes the dual LM2904LV-Q1 and quad LM2902LV-Q1 operational amplifiers, or op amps. The devices can operate in a supply range of 2.7 V to 5.5 V.

These op amps serves as supply an alternatives to the LM2904-Q1 and LM2902-Q1 in low-voltage applications that are sensitive to cost. The LM290xLV-Q1 devices provide better performance than the LM290x-Q1 devices at low voltage and have lower power consumption. The op amps are stable at unity gain, and do not have phase reversal in overdrive conditions. The design for ESD gives the LM290xLV-Q1 family an HBM specification of 2 kV.

The LM290xLV-Q1 family is available in packages that match industry standards. The available packages include SOIC, VSSOP, and TSSOP packages.

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。
