會員注冊CA1458，CA1558（雙運放）;CA741C，CA741，LM741（單運放）是高增益運算放大器，用于軍事，工業(yè)和商業(yè)應(yīng)用.這類單片硅集成電路器件提供輸出短路保護(hù)和閉鎖自由運作。這些類型還具有廣泛的共同模式，差模信號范圍和低失調(diào)電壓調(diào)零能力與使用適當(dāng)?shù)碾娢弧?0kΩ電位器是用于抵消調(diào)零類型CA741C，CA741（見圖4 ）
類型CA1458，CA1558沒有具體的終端抵消調(diào)零。每一類運放包括一個差分輸入放大器有效驅(qū)動增益和發(fā)射極跟隨互補(bǔ)輸出。
技術(shù)數(shù)據(jù)類型與相應(yīng)的臺灣CA品牌同類型。
