OK, I will let them stay in the socket but it's only one per round possible, so this will take same time. Will I get much improvement replacing the regulators for 15V range, or would it be just slight? I don't want to do it aimlessly as I will lose possibility of using some chips. Depends on the ... Virtual ground and stability driving a capacitive load ... Virtual ground and stability driving a capacitive load ... LM317 regulator to supply the 24V, and an op amp and a simple push pull circuit with discrete transistors to supply the virtual ground. The discrete transistors are there because the op amps I had available couldn't supply enough current. This all seemed to work great, however, I ... Op amp integrator Referring to the above diagram, if the op amp is assumed to be ideal, nodes v 1 and v 2 are held equal, and so v 2 is a virtual ground. The input voltage passes a current through the resistor producing a compensating current flow through the series capacitor to maintain the virtual ground. This charges or discharges the capacitor over time. Differential amplifier A differential amplifier is a type of electronic amplifier that amplifies the difference between two input voltages but suppresses any voltage common to the two inputs. It is an analog circuit with two inputs − and and one output in which the output is ideally proportional to the difference between the two voltages = ( − −) where is the gain of the amplifier. power supply Virtual earth (ground) or "mid rail ... Virtual earth (ground) or “mid rail generator” ... An active virtual ground circuit is sometimes called a rail splitter. ... There are of course explicit buffers (linear regulators, op amps, discrete parts in a buffer formation), which is more of what they mean when they say "active." share | improve this answer. edited Jan 19 '16 at 9:34. mix buss topologies If I recall correctly, API's summing buss uses the standard approach of a long, unbalanced low impedance (virtual ground) summing buss. The main differences versus a 5532 would be The API opamp is discrete in a potted module several times the size of a 5532. The Virtual Ground – Mastering Electronics Design The inverting input is at a zero potential, therefore virtual ground, which is a direct consequence of the feedback provided by R2 and the op amp high gain. Let’s see why. Figure 2. This time let’s consider that the op amp does not have an infinite gain. Let’s consider it finite and note it with A, as in Figure 2.
