Hello guys
I have been working on two of the PCB, and when finished, I will post some pics tomorrow morning if possible, if not, it will be in afternoon.

Hello
Here is a bad photo for the 3 PCBs taken by a WebCam, as you can see guys, I have been suffering with the WebCams recently, any way, the PCBs are pretty nice and cool...

Good! I work on the dang things all day long (network engineer), so I can understand the frustration when they don't work properly 😀 That's something they're definitely good at!
ok, it's time to get this thread up and running again.
after quite a slogstorm and what apprears to be a premateur death, i think it's time to get some work done here.
a lot of good ideas have been put forth, and i have some of my own brewing in the back of my head, and that wil most likley be put forth sometime soon.
there has altso been some talk behing the curtains, that will probably yield fruits soon.
my original samples from national altso got lost in the mail, but new ones are comming with the good graces of National semiconductors. 😉
so stay tuned, and stay focused on the task at hand people.
i think this could be the foundation of a great piece of audio equipment.
Cheers

Update
I'm just checking in to see how this thread it going. Metal, i could not read your pics, i wonder if my mac just can't read these particular pics. I got an email from NSC saying that the chips will be shipped out from Singapore this week so i hope these don't get lost.....
Cheers

Hey fuys
Don't get frustrated, I have not received any samples yet, n o problem, they will arrive finally 🙂
Good luck for all of you 🙂

"There is hope"
Well i have just recieved two LM4780TA's which I placed around the same time as the LM4702's s so maybe they will deliver them after all.....

Hmmmmmmm
I couldn't open any of your pics, metal.
Got an email from Singapore saying they are out of stock but will be re-sending my order asap.

i got that mail a week ago too, havn't heard anything yet though.
geez, National is slow.
both the Ti and Analog suff i got at the same time has arrived.

It isn't obvious to me that the output devices are limited to Darlingtons. That may have just been intended as a minimal component example. I don't see why you couldn't uses quite a number of output topoligies; EF tripples, CFB and so on. In fact, an obvious (to me) application would be a more or less standard IS+VAS with which to experiment with a variety of output schemes. Perhaps even a pair of lateral MOSFETs.
Apparently National has cancelled orders for LM4702 samples and asked folks to resubmit at a later date. The email came yesterday.

Mine came a week ago. Cancelled. Please resubmit.
I think it's probably still in a very 'preliminary' stage of production.
Like the datasheet. 😀
This came 12-04:
This device was not in stock in our Singapore warehouse and
is backordered. This means that your delivery will be delayed
beyond the typical 3-7 days.
Please do not resubmit your sample request for the same device,
as we will continue to process this order as soon as we can.

You receive that message first.
Some time after that, you will receive the same message Jack and I received: cancelled.
I see I am a little late to the game, but I just found out about this part. From what I have seen, the designs you guys have so far look like a great starting point for a pretty sweet and POWERFUL amp. I am especially interesed in hearing if you guys who have chips have had a chance to take a listen yet.
I was originally interested in using this chip in a dedicated sub amp, but since there seems to be no availability for another 3 months. . . . 🙁
