| Abstract: | The main specifications of wideband, low noise integrated operational amplifier OPA686 are introduced, as well as the technical details such as parasitical effect, selecting and placement of components, which should be taken into account in designing wideband, high performance preamplifiers. The schematic bandwidth circuit diagrams of a DC - amplifier and an AC - amplifier are provided. Experimental results show that OPA686 is an ideal device to design wideband preamplifiers. |
