The LMC7101 device is a high-performance CMOS operational amplifier available in the space-saving 5-pin SOT-23 tiny package. This makes the LMC7101 ideal for space- and weight-critical designs. The performance is similar to a single amplifier of the LMC6482 and LMC6484 types, with rail-to-rail input and output, high open-loop gain, low distortion, and low-supply currents.

The main benefits of the tiny package are most apparent in small portable electronic devices, such as mobile phones, pagers, notebook computers, personal digital assistants, and PCMCIA cards. The tiny amplifiers can be placed on a board where they are needed, thus simplifying board layout.

CIRCUIT060023 — 反相加法器電路

This design sums (adds) and inverts two input signals, Vi1 and Vi2. The input signals typically come from lowimpedance sources because the input impedance of this circuit is determined by the input resistors, R1 and R2. The common-mode voltage of an inverting amplifier is equal to the voltage (...)

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。
