摘　　要：运算放大器作为一种基本器件应用广泛,可以完成信号放大、信号运算、信号处理、波形产生和变换的工作。运算放大器在应用中直接接入容性负载,会导致输出产生振荡,并伴随异常发热情况。针对这一故障,分析了根本原因,并给出了故障处理过程。As a basic device,the operational amplifier is widely applied,and can complete works such as signal amplification,signal operation,signal processing,wave generation and transformation.Capacitive load accesses directly to the operational amplifier,will result in output oscillation of the operational amplifier with unusual heating.The root cause on this fault was analyzed,and the fault handling process was given.

关 键 词：运算放大器 容性负载 输出 振荡 分析
