  1. Operational Amplifiers, or Op-amps as they are more commonly called, are one of the basic building blocks of Analogue Electronic Circuits. In this operational amplifier basics tutorial, we will see that Operational amplifiers are linear devices which have all the properties required for nearly ideal DC amplification.

  2. An operational amplifier (often op amp or opamp) is a DC-coupled electronic voltage amplifier with a differential input, a (usually) single-ended output, [1] and an extremely high gain. Its name comes from its original use of performing mathematical operations in analog computers.

  3. 运算放大器 (英語: Operational Amplifier ,缩写: op amp 或 opamp ),简称 运放 ,是一种 直流耦合 ,差模(差動模式)輸入、通常為單端輸出(Differential-in, single-ended output) [1] 的高增益(gain) 電壓 放大器 。 运算放大器能产生一个比输入端 电势差 大数十万倍的输出电势(对地而言)。 [2] 因为刚开始主要用于 加法 , 減法 等類比运算电路中,因而得名。 通常使用運算放大器時,會將其輸出端與其 反相輸入端 (inverting input node)連接,形成一 負反馈 組態。 原因是運算放大器的電壓增益非常大,範圍從數百至數萬倍不等,使用 負回授 方可保證電路的穩定運作。

  4. 運算放大器 (英語: Operational Amplifier ,縮寫: op amp 或 opamp ),簡稱 運放 ,是一種 直流耦合 ,差模(差動模式)輸入、通常為單端輸出(Differential-in, single-ended output) [1] 的高增益(gain) 電壓 放大器 。 運算放大器能產生一個比輸入端 電勢差 大數十萬倍的輸出電勢(對地而言)。 [2] 因為剛開始主要用於 加法 , 減法 等類比運算電路中,因而得名。 通常使用運算放大器時,會將其輸出端與其 反相輸入端 (inverting input node)連接,形成一 負回授 組態。 原因是運算放大器的電壓增益非常大,範圍從數百至數萬倍不等,使用 負回授 方可保證電路的穩定運作。

  5. Operational Amplifiers, also known as Op-amps, are basically a voltage amplifying device designed to be used with components like capacitors and resistors, between its in/out terminals. They are essentially a core part of analog devices.

  6. Operational Amplifier Circuits as Computational Devices So far we have explored the use of op amps to multiply a signal by a constant. For the inverting amplifier the multiplication constant is the gain R2. −. R1and for the non inverting amplifier the multiplication constant is the gain R2. 1+.
