The LM747 is a general purpose dual operational amplifier. The two amplifiers share a common bias network and power supply leads. Otherwise, their operation is completely independent.

Additional features of the LM747 are: no latch-up when input common mode range is exceeded, freedom from oscillations, and package flexibility.

The LM747C/LM747E is identical to the LM747/LM747A except that the LM747C/LM747E has its specifications guaranteed over the temperature range from 0°C to +70°C instead of -55°C to +125°C.

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。
