Apr 24, 2012 · Output voltage swing is defined as the maximum positive or negative peak output voltage that can be obtained without wave form clipping, when quiescent DC output voltage is zero.
The smaller the output short circuit current is, the closer the amplifier will swing to the rail. The voltage output swing capability of an op-amp is dependent on the op-amp output stage design and the load current. In to the graph above we can clearly see the difference between these concepts such as rail to rail, headroom, V OH and V OL.
Jun 19, 2011 · Swing is the difference of maximum output voltage and minimum output voltage. Maximum possible swing in output you can have is VDD-VSS. where VDD is most positive voltage and VSS is most negative voltage. It does not mean that your swing is VDD-VSS. It may be smaller than this. This depends on circuit design. For CMOS logic family it is VDD-GND. It means CMOS logic family have full voltage swing.
and load resistor as shown in Figure 2-1b. To allow for maximum output voltage swing the Q-point should lie approximately halfway between Vdd and the edge of the ohmic region, shown in the figure as Vknee. If the drain current or load resistor is too large, the device will swing into the ohmic region during operation leading to
May 21, 2019 · You will notice that this headroom voltage increases as the current load increases. For VS = 3V and IL = 5mA, for instance, the minimum possible VOH would be V+ - 600mV and for VS = 3V and IL = -5mA, the maximum possible VOL will be V- + 260mV. The resulting values will define the minimum possible output voltage swing.
Aug 19, 2021 · I have highlighted an output swing of 10V and -10V (instead of -11V and 11V) since it was easier. As you can see for 10V, the output source current reaches ~20mA; however, for -10V, the output sink current ~15mA. Therefore in the scenario of the negative output swing being less than the positive output swing is expected. All the best, Carolina
The output swing, assuming you operate the circuit within its linear regime, is just. v o = A v o v i. so 0.995 v i. It can't be brought down to a numerical value since v i hasn't been specified. The maximum output voltage (when operating linearly) is roughly V C C − V c e, s a t, or 9.7 V.
Sep 05, 2017 · The correct way to set the optimal operating point, assuming maximum symmetric output swing is the criterion, is to center it on the AC load line. This is what your bolded sentence describes. Using the midpoint of the DC load line is a shortcut that often works well enough.
How are DFPs Distributed? And we use the term regulation to talk about the effect of "stabilizing" an output voltage. Active 4 years ago. The smaller the output short circuit current is, the closer the amplifier will swing to the rail. I'a attaching the simulation file, which will gives you my VIN spec too.

Output Voltage Swing defines how close the op-amp output can be driven to rail to rail either power rail: V DD or V SS under defined operating conditions where the op-amp still can function correctly. The key to comparing voltage output swing specifications is to determine the amount of current that the amplifier is sinking or sourcing. The smaller the output short circuit current is, the closer the amplifier will swing to the rail. The voltage output swing capability of an op-amp is dependent on the op-amp output stage design and the load current. In to the graph above we can clearly see the difference between these concepts such as rail to rail, headroom, V OH and V OL. The input voltage range restrictions are critical in op-amp circuit applications. In a closed-loop configuration, using a voltage beyond the input voltage range sometimes looks like an output limit problem, but in fact is an input range problem. Return to Top.

What is the voltage output for a throttle position sensor for a Plymouth voyager? Hello Kai, same load is there for both positive and negative output voltage. Or have you thought about using asymmetric bipolar supply voltages? The input voltage range restrictions are critical in op-amp circuit applications. Hi Suresh, this is another method to improve the symmetry of output voltage swing: Kai. With these structures, the output voltage swing is only limited by the saturation voltage bipolar or the on resistance CMOS of the output transistors, and the load being driven.

Then the following problem created a doubt as I failed to recognize that in the next problem AC load line is the same as DC load line.
Can you please add a schematic? I know you describe your circuit but it is hard to visualize clearly. I have highlighted an output swing of 10V and V instead of V and 11V since it was easier. Therefore in the scenario of the negative output swing being less than the positive output swing is expected. What is connected to the output of LM? Seems like the OPAmp sees different loads for positive and negative output voltage. Insert a R isolation resistor when measuring the output voltage of LM Saturation voltage is not only asymmetric for both swing polarities but also alters with temperature. Can you decrease the feedback resistances? Then you could eventually add two low leakage zener diodes. As per the application demand one of the parameter to check saturation limit and requirement is symmetric,. I can't decrease the feedback resistor, that will effect to other parameters and it won't make output swing symmetric. LM does not have a symmetric VOM. Where in the data sheet does it claim sysmetric?
