The LMC7101 device is a high-performance, automotive, CMOS operational amplifier available in a space-saving, 5-pin, SOT-23 tiny package. This design makes the LMC7101 an excellent choice for space- and weight-critical designs. The performance is similar to the single amplifier of the LMC6482 and LMC6484, 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 needed, thus simplifying board layout.

CIRCUIT060023 — 反相加法器電路

此設計會對 Vi1 和 Vi2 這兩個輸入訊號求和 (相加) 並反相。輸入訊號通常來自低阻抗源,因為此電路的輸入阻抗由輸入電阻器 R1 和 R2 決定。反相放大器的共模電壓等於連接至非反相節點的電壓,在此設計中即為接地。
