运算放大器在携带式电子仪器,遥控等限制使用功率的情形下,低功率运算放大器是很有用的。在测量爆炸性危险物品时,外加电压受到限制或者在有源滤波器中也是很适用的。特别是在有源滤波器设计时,在有源电路部分LC滤波器中没有功耗产生的实际设计时,也是个很重要的因素。本来,显而易见,我们希望其特性得到满足,在无信号时的功耗尽可能小。但近几年来,设备规模向庞大方面发展,由功耗而产生的“热”就限制了组装。
Operational Amplifiers Low-power operational amplifiers are useful in applications where power is limited by portable electronics, remote controls, etc. In the measurement of explosive dangerous goods, the applied voltage is limited or active filter is also very applicable. Especially in the active filter design, the active circuit part of the LC filter does not produce the actual design of power consumption is also a very important factor. Originally, it was obvious that we wanted its features to be satisfied, with as little power as possible without signal. However, in recent years, the scale of equipment to a huge development, the power generated by the “heat” to limit the assembly.
