Web28 de abr. de 2024 · A Hi-Z point is one connected to a very high resistance so no current can flow. In your schematic NO wire (neither of 1,2,3,4) is Hi-Z because if you connect one of them to GND, current starts flowing and the LED lights up. UPDATE: Wire number 3 can actually be Hi-Z, provided that the resistor attached to it has a very high ohmic value. Web7 de abr. de 2014 · There are two basic methods to accomplish higher voltage input ranges at very high input impedances. 1) Use a high voltage Op Amp for the input device. 2) Bootstrap a lower voltage Op Amp so it can handle far higher voltages. Of these two approaches #1 is fairly easy to accomplish. The LTC6090 from Linear Technology has +- …
