Here is my latest amplifier module hot off the press!
The NXP180 Dual Die Lateral Amplifier Module.
It measures only 50mm x 50mm
Almost all of the components are SMD
It has very low Noise and Distortion as shown in the THD+N and FFT Graphs below.
The THD+N is flat from 5hz-20khz @ 0.006%
It is capable of power levels as high as 300 watts into 4 Ohms
and >200 watts into 8 Ohms.
All these measurements were done on a ATS-2 AP
Prototype module shown below.

Looks good, should make a very nice 60watt amp with low impedant drive, but what will they cost 🙂
Hi tinitus
It will sell for around 55 Euro ($89.00AUD)plus postage and handling.
and will be fully assembled and tested.
I am expecting to have them released sometime in march 2008.
I hope this helps 🙂

WOW! You might sell tons of those 😉 got an itche to make active speakers 😀
No bias adjustnent, or is that a tiny little smd pot i see ?

Hi Antony
What are we looking at for min/max voltage rails? I might well have a use for half a dozen of those. 😉

Hi Tinitus
Yes I hope so, They sound most excellent as well.
because of their small size and performance they are well suited to 5-7 channel amplifiers.
There are plans also to release a high powered SMPS based on a
new SMPS IC which uses a new type of switching technology that removes any remaining dissapation found in the output stage when using a conventional smps IC such as the SG3525 IC.
200 watts can be produced without any heatsinking at all and 400 watts with only a metal plate as a heatsink.
Higher powers at done using one of our own ICs which is based on the same technology.
The idea would be for DIY's to make a very small high quality multi channel amplifier using these modules and one of these smps at a very cheap price, which at the end of the day is at the heart of DIY audio. 😀

Sorry Tinitus I missed your other question.
Yes there is a small SMD trimpot for bias adjustment...🙂

This interests me. What's the average effiency, and how much power does it typically draw at idle? Also, I'm very interested in your SMPS if it's priced as well as this module seems to be.
Hi DonoMan
The efficency is the same as any other Class-B amplifier around 60%.
Idle power is around 8 watts with a +-70 volt rail.

Sorry but I'm completely confused. Why are all of you talking about SMPS (Switched Mode Power Supply, I presume) in the same breath as a linear analog amplifier circuit? And what ICs are you all referring to? I thought this amp has a conventional discrete OPS made of a pair of L-MOSFETs? 🙁
Hi tcpip
The original project was to include a SMPS.
So that is why it was mentioned.
It was to use the FSFR2100 half-bridge resonant power switch from Fairchild.
This particular amplifier will not be released now in the advertised
form as the Dual Die mosfets that is uses are no longer available to me.
I have now redesigned the NXP180 to use 2SK1530 and 2SJ201
MOSFETs and it has been renamed the NXV200
More details on this change will be available on my web site by early next week.

Nice design no doubt but are you aware of that NXP is a semiconductor company?The Saint said:

Hi Peranders
I wasn't aware actually 🙂
But it doesn't matter now as it is now the NXV200
With 2SK1530 and 2SJ201 Mosfets
I think Honda makes a NX150 motorcycle as well.
Shame about that one...😱

What does NXP stand for?
Next Experience (formerly Philips Semiconductors)
no abbreviation matches for NXV

Ha Ha Ha.....
Thanks Peranders, I will be sure to check it out next time.
The NX series was originally stand for "Next Generation"
Because the AV series of amplifiers I did was the First Generation
Then came the NX series. Most of these were N-channel designs
with exception to the NX150 and a version of the NX400 with was called the NX400NP because that version had a N & P mosfets in the output stage.
and so came the NXP which really wasn't an acronym.
So much as it stood for next generation with an N&P output stage.
So NXV stands for Next Generation with VFET output stage
I hope that makes sense.... 🙂
