５０００倍精密绝缘放大器郝鸿安在机电一体化电子设备中，不少传感信号与强电混杂在一起，而传感信号常常要送到不耐受电冲击的弱电处理系统，例如微机设备、自动打印记录器等。在这种情况下，传感微弱信号的放大，以及与强电系统的绝缘隔离是不可缺少的。附图所示电路可... 5000 times Precision Insulation Amplifier HAO Hong-An In mechatronic electronics, many of the sensing signals are mixed with strong current, and the sensing signals are often sent to weak processing systems that are not resistant to electric shocks, such as microcomputer devices, automatic printing Recorder and so on. In this case, the sensing weak signal amplification, as well as the isolation of the strong electrical system is indispensable. The circuit shown in the figure can be ...
