When driven with enough current, the device will follow the ‘new’ linear curve, since it is balancing out the nonlinear gate capacitance.

This eases the design of the bias servo. An example would work nicely here Product Tags Add Your Tags: Below is the final simplified schematic of the entire amplifier After fixing the problem by adding a class AB driver, distortion was greatly decreased Note that this s2k1530 applies if the device is used in linear mode.

Use a current mirror with the LTP input to get as much gain as possible to allow for negative feedback, but do not solely rely on the feedback to make the amplifier better.

I promise it is not hard. This is a minefield, and I suggest that you tread very carefully. Customers who bought this product also bought: It can also cause major problems in switching circuits, but that’s another topic altogether and will not be covered here.

Only registered users can post a review. This process continues dqtasheet the cell fails due to over temperature, at which point the MOSFET suffers catastrophic failure. The modularity and ease of implementation makes it a reference choice for any dual mono stereo DIY amplifier project or the realization of multichannel amplifiers.

The lower impedance of the driver stage the better. These transistors are controlled by the integrated driver ” LME” with an advanced overload protection system “Soft Clipping”.

You have no items in your shopping cart. This product is no longer in stock. Even this will not show the same effects as a true valve amp – the nature of the distortion components will almost certainly be different.


To balance out the nonlinear curve, we can simply cut if off where it seems too bad by using bias. V DS sat will normally be in the order of around 12V gate shorted to drain at a current of amps, so R DS on ddatasheet in the order of 1.

The secure code is incorrect. Equipped with precision metal resistors, high quality capacitors, this kit is ideal for high-power amplifier modules with high fidelity quality sound that favors harmonics of type 2 tube sound. Make sure you check the idle current before calling the design done!

While this scenario is not common in switching application, if the MOSFET is used linearly it is very real, and has caused problems in the past.

These devices daatasheet extremely rugged, yet they do have a large nonlinear gate capacitance to deal with. Please try dtaasheet later.

They are much more rugged than BJTs as my burned parts pile shows, and sound very good when a class AB driver is added. It is probable that the constructor will be forced to compromise, using a significantly lower quiescent current than suggested just to maintain a sensible heatsink size and temperature.

Don’t add these yet!

The large notch is at the second harmonic, and the small bump to datashet right is the fourth harmonic. Reducing the gate resistors to 4.

Only lateral MOSFETs provide a crossover point on their transfer characteristics that is low enough for linear operation. We want to measure what the load is doing, not what it should be doing.

Through a lot of time and molten breadboards, I found dataheet best two things to design for darasheet the following:. Better performance can be seen by using multiple LTPs, but this will not be a simple design in fact it will be quite complex with high frequency stability issues needing attention.


A compact and nicely wired PCB should decrease distortion even further. Specifications Contact Us Ordering Guides. BJTs are often used, but they do not respond well to even momentary overloads. Sign Up for Our Newsletter: Amplifier quiescent current from the current level of precision adjustable resistance adjustment, Datashert enthusiasts can adjust according to your liking different tones 6.

Accessories for this product. Based on the above, it is quite apparent that vertical MOSFETs can easily get into thermal runaway if the bias servo is datashedt set up correctly. The value for R7 will depend on the linearity of the driver transistors. This does not mean use an inadequate heatsink, but the bias between devices should be a bit more than many are used to.

This will cause it to get hotter, so the threshold voltage will fall further and it will 2sk11530 draw more current, causing it to get still hotter. Any device can be used for audio and give great performance if a proper design is found.

LME Download While it worked well enough, giving the expected power output and with fairly low distortion, as noted above the required bias current is quite high to reduce crossover distortion to an acceptable figure. That is why we need to buy 22sk1530 few extra and match them together.

See the IR application note for more catasheet information [ 4 ]. Indeed, two of the articles listed below refer to the fact that using a HEXFET much bigger than needed to provide a safety margin has exactly the opposite effect.
