The bandwidth is 3,6Hz to Don’t add these yet! Power amplification stage based on Q7 and Q8 which operates in the class Datawheet mode.


Laser Module Call us now toll free: I am planning to fix all these circuits in a single casing so can i use a single transformer to the entire system, if yes please specify the voltage and amps. If you try to build, it will not work, 2sj2001 they have not included a lot, what you see is only the tip of the ice-burg.

For some further reductions in distortion, the following work quite well: Also note the capacitor in parallel with R7. While this is true to an extent, it is obvious that it is not a general rule upon which one should rely in all circumstances. Lateral MOSFETs as used in P have exactly the same issue, but the curve changes from negative to positive at a much lower current around mAand this is visible on the transfer characteristic graph but you will need to look for it carefully – it is not specified in a useful manner IMO.


Thank you sir jithin pv. Hi… plz, provide me the pcb layout. A careful examination shows that the ‘inflection’ point is actually the region where the negative temperature coefficient of V GS exactly compensates for the positive temperature coefficient of R DS on.

This eases the design of the bias servo. Why not use a single capacitor?

Using HEXFETs in High Fidelity Audio

A compact and nicely wired PCB should decrease distortion even further. Now, in order to size-up the proper driver for the FETs, we need to do a little maths.

The network comprising of capacitor C3 and resistor R19 improves high frequency stability and prevents the chance of oscillation. It will continue to cause problems if designers are unaware that this failure mode even exists – after all, most comments seen describe MOSFETs as almost indestructible.

The amplifier can be also used as a sub woofer amplifier but a subwoofer filter stage has to be added before the input stage. Dataheet the root of this problem be an overheated transistor when soldering? The positive coefficient of R DS on is insignificant at the current levels needed for setting quiescent current accurately.


That it is possible to build a valve amp to a high specification is not in doubt, but they tend to be complex and expensive. This greatly improved the amplifier. Requests for component values will not be fulfilled.

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.

This must remain a very good reason to stay clear of these devices for audio, unless you datashheet fully aware of the potential risks, and how to avoid them. This application note also mentions the possibility of a failure mode similar to second breakdown when operating switching MOSFETs as linear amplifiers.

These devices are now obsolete, but they were classified for V GS offwith ‘0’ classed devices having a threshold voltage of 0. It looks very simple, and includes the class AB driving stage to improve gate driving. I disconnected the circuit from mains quicker than the fuses.

The minimum stability network Zobel shown is always needed, and datasheeet series inductor with parallel resistor may also be required. However, most of the early types are obsolete, and their nominal replacements are ‘better’ in that R DS on is lower than the previous version s.
