Operational Amplifier（運算放大器） 是一種高增益的電子電壓放大器，通常用于模拟電路中對信號進行放大、濾波、運算等操作。以下是詳細解釋：
運算放大器是模拟電路設計的核心元件，廣泛應用于信號處理、控制系統、傳感器接口等領域。其理想化模型簡化了電路分析，但實際設計需結合具體型號的參數（如LM741、OPA2134等）。
運算放大器是一種電子放大器，用于放大和處理模拟信號。它通常由多個晶體管和其他電子元件組成，具有高增益、高輸入阻抗和低輸出阻抗等特點。運算放大器廣泛應用于電子學領域，例如信號放大、濾波、比較、積分和微分等應用。
運算放大器通常用于電子電路中，可以用來放大信號、濾波、比較信號等等。它的輸入可以來自傳感器、麥克風、電視機等等。輸出可以連接到顯示屏、揚聲器、計算機等等。在使用運算放大器時，需要根據具體的應用場景選擇不同的型號和參數。
運算放大器是一種電子放大器，它可以放大輸入信號的幅度，并且可以通過外部電路進行反饋控制。它通常由一個差分放大器和一個輸出放大器組成，具有很高的增益和輸入阻抗。運算放大器還可以用來進行數學運算，例如加法、減法、乘法和除法等。
運算放大器的近義詞包括：op amp、差分放大器、運放等。
運算放大器的反義詞是非運算放大器，也稱作普通放大器。與運算放大器不同，非運算放大器隻能放大信號的幅度，但不能進行數學運算。非運算放大器通常由一個普通放大器組成，沒有反饋電路，增益和輸入阻抗也比較低。
