Noninverting differential and Inverting Differential

[watertreader]

Hi,

Is there a differential amplifier type known as non-inverting differential or the other case, the inverting differential

Thanks

hi dear,

Nonlinear imperfections
Saturation — output voltage is limited to a peak value, usually slightly less than the power supply voltage. Saturation occurs when the differential input voltage is too high for the op-amp's gain, driving the output level to that peak value.
Slewing — the amplifier's output voltage reaches its maximum rate of change. Measured as the slew rate, it is usually specified in volts per microsecond. When slewing occurs, further increases in the input signal have no effect on the rate of change of the output. Slewing is usually caused by internal capacitances in the amplifier, especially those used to implement its frequency compensation.
Non-linear transfer function — The output voltage may not be accurately proportional to the difference between the input voltages. It is commonly called distortion when the input signal is a waveform. This effect will be very small in a practical circuit if substantial negative feedback is used.

Urgh... I am not too sure of your explanation. Did you answer the correct topic?

ya.. an opamp.

Hi,

Do they mean the same type of Op-amp or they are different op-amp form?

Thanks

hi

I AM TALKING ABOUT THE SAME ONE YOUY ARE LOOKING FOR.

 

[watertreader]

Perhaps you can elaborate? I am asking about whether there is such a form of op -amp called Noninverting differential or Inverting Differential. How do they differ?

are you asking for the internal structure of an opamp?? i want to leran too

 

[amriths04]

the same opamp. if the input is given to one transistor(-ve) of the differential pair keeping the other grounded it acts as an inverting amplifier and vice versa.
