Figure 1. Op amp output saturation produces a clipped signal. Image used courtesy of Robert Keim Saturation leads to a complete loss of correspondence between the input waveform and the output waveform. However, output swing performance can degrade even before the saturation point is reached. Applic...
An op amp circuit utilizes an improved current mirror circuit that includes a first transistor connected to a second transistor such that their sources and gates are commonly connected. A resistive element is connected between the drain and the gate of the first transistor such that a current ...
For an input of 9-12 volts DC, I need an output 0-12 volts DC where the op-amp rails are 0 and 12 volts. A DC sweep on V1 from 9 to 12 volts shows this working in CircuitLab but not on my LM358 in the real world. Is there an op-amp better suited for this application? b...

It is usually caused when one of the internal stages of the op amp no longer has sufficient bias voltage across it and subsequently turns off. This causes the output voltage to swing to the opposite rail until the input comes back within the common- mode range, as shown in Figure 1 for...

In simple terms, theoutput voltage swing is the range of voltage that an opamp phisically provide at its output. For example, for a load >2K, the 741 can swing to within about 2 volts of the supply (+/-15V). Op-amps with MOS transistor outputs(CA3130 and CA3160) can swing all th...

When configured properly, the output voltage swing of the LMH0302 will be 800mV p-p. There are two main factors that will determine the output voltage swing: one is the resistor between Rref and Vcc - this should be 750Ohms, the other is the load that is being driven by the d...
swing when driving a stated value of load, typically 2–10kΩ. The “rail-to-rail” op-amps with CMOS output will in fact only give a full rail-to-rail swing if they are driven into an open circuit; any output load, including, of course, thefeedback resistor, reduces the total ...
