Is 0811 ADC chip easy to get ?

I’m thinking of putting the 0811 from National in one of my designs..
When I ordered a few samples from my local supplier there were some
confusion wether it is a easy-to-get chip or not..

Anyone know if it will be avaliable in large (k) amounths in a few
years from now ?

..by the way – I’ll be using SOIC-capsule..

Any ideas on how to boost telephone REN (Ringer Equivalency Number)

Does anybody know of a device or component that I can insert into the
telephone line that can boost the ringer equivalency capacity of the
system. Such a device would have to be an amplifier of some sort.

The problem I have is I installed an ISDN terminal adapter (Ascend 25)
and am now running the phones in my house off of it. Normally the
phone company puts out/supports an REN of 5 which rings all 5 phones
in my house (I added up the actual RENs  and they come to 2.3 – no
problem). However, they cut costs in these adpter boxes and they only
support an REN of 2 !!!  So I can only run 3 out of the 5 phones I
have. Any ideas how I can get my other 2 phones to ring?

Any and all suggestions are welcome.

Thanx,

Microwave Sensors – cheap source?

I’m searching for some microwave sensors (a la supermarket automatic door use)
to experiment with.  Where can I get some at less than new pricing, ($400
a shot?)  They don’t have to be new, in spec, or even completely
functional.  None of the commercial door installers in my area have any
they’re willing to part with…

Thanks for any tips.  Email to

miwe…@davidson.edu

appreciated, but I read here too.  

Thanks a million,

Mike

WTB: 500 Pcs. TL505CN

Hi!

I’m posting this for a friend of mine who doesn’t have internet
access.
He is looking for abt. 500 TL 505 CN, a dual slope 10 bit ADC.
This is probably an outdated chip, I did find it in a 1985 Ti
list, but there are no suppliers in Germany.
So if you have some in stock you want to get rid of send an
offer with a postal address to:

Stefan.Hen…@math.uni-giessen.de

or:

Stefan Hennig
Am Rasen 15

Thanx in advance,

24C16 EEPROM failing: why????

I am having a problem with retaining data in a 24C16 serial EEPROM. After a
few days, the data seems to get "lost", probably during powerup. Has
anyone had a similar experience or know of a good fix? I would doubt that
the proper address is sent to the chip during startup.

Any help appreciated.
