They exist, but are probably considered ‘exotic’ by most suppliers. The update below has some important information that I recommend you read thoroughly and make sure you understand before settling on the use of HEXFETs in your next amp project.

An example would work nicely here I suggest that high voltage, relatively low current devices are preferable to the reverse, as they will have an inherently higher R DS onand therefore a lower inflection point. Likewise, the peak current should also be much lower than the rated maximum.

This should be of a high value i. The spec is given below, datsheet I have some doubts regarding the project. The lower impedance of the driver stage the better.

Finding the correct design parameters becomes more complex with non-linear devices. Once things are fine set current adjusting pot to minimum value switch on with new MOSFETS and with a dummy load of 25 ohms without speaker. Can i use it as a subwoofr amp? Hi Niklas in the place of R8 put a link. Further searching revealed a document from Solid State Optronics [ 3 ]where the temperature coefficient for V GS is said to be You may also like: Your email address will not be published.

Hi Harry as per following link it is a good performer. Design a compact PCB layout with feedback taken from as dwtasheet as possible to the load terminal. However, the two are directly related, so the point is moot. The exact values around the Vbe multiplier also known as a datasueet servo are critical to ensure that the thermal performance is matched as closely as possible. Thanks for the help.

This is because they suffer from second-breakdown – an instantaneous and catastrophic failure mode.

This eases the design of the bias servo. Although the requirement for this is minimal the CD format is incapable of anything even approaching a square wave above a couple of kHzit has become an expectation that power amps should be able to reproduce perfect square waves at 10kHz as a minimum.

Thank you sir, god bless you. You cannot use 25 volt transformer. When driven with enough current, the device will follow the ‘new’ linear curve, since it is balancing out the nonlinear gate capacitance.

Feel free to read that again to make sure that you understand the ramifications. Do the tweeter have impedence? For a better understanding, a simplified output stage circuit is dataaheet below.

This must remain a very good reason to stay clear of these devices for audio, unless you are fully aware of the potential risks, and how to avoid them. They are much more rugged than BJTs as my burned parts pile shows, and sound very good when a class AB driver is added. I have volt 3amp.


Well, that is the easy route to itfp9240 for designing an output stage. Better performance can be seen by using multiple LTPs, but this will not be datasehet simple design in fact it will be quite complex with high frequency stability issues needing attention. The value for R7 will depend on the linearity of the driver transistors. A compact and nicely wired PCB should decrease distortion even further.

If you are designing a class A amplifier, the first trick see below should be used the second is not needed since the bias is already quite high.

I need watts rms amplifier circuit diagram. It is just easier to use more linear devices. Normalising simply means that everything is taken back to a reference of unity, so simply multiply the claimed V th by the figure shown along the left side, for the temperature at which your device will operate.

The graph was taken from the IRF data sheet, but has been colour coded to make identification of each graph easier. Note that the article above does not address this potential failure mode, nor do many othersand your datasheeg choice is to find MOSFETs where the thermal ‘changeover’ occurs at the lowest possible drain current.
