Hi Group,
I am interested to have the datasheets for the above chips. I’ve
looked into the OKI websites but they seem not to have the datasheet.
Is the 8755 only made by intel or was it second courced by NEC or
Mitsubishi ?
If someone has the old data book, I would be most grateful if you can
scan the sheets on how to program the eprom inside the chip.
TIA.

I used MAX712 IC to build a Nimh battery charger. I experienced that
712 cannot terminate charging properly, either overcharged or terminate
charging too early.
I don’t think zero dV/dt termination method is good and I never found
there is a max voltage termination method included in MAX 712.
almost 30% times when I used this MAX712 to charge 4 AA batteries, the
problem (terminated too early) occurred. Really don’t think 712 can
work well !
Hallo everybody,
is there anyone who have experienced problems with power supply swithing
using ST Viper12 IC?
I’m guessing about components shorted in my application.
Thanks a lot

I had always lived in the belief that a 15W soldering iron ran cooler
than a 35W iron but recently I read something which said they both
run at the same temp.
Presumably the real difference is the speed at which the iron reheats
once the thermostat kicks in to say the iron is too cool.
I’m in the Uk and I currently use a 25W Antex. It seems to "run out
of heat" all too often when I am soldering undemanding things like a
fine wires to small tag.
If the temp is the same then would I be ok using something like a 35W
iron even for working on electronics components.
This is probably a rare need these days — but are there any rail-to-rail
op-amps (both input and output) that can handle +/-15V supplies? My search
through Linear Technology, Analog Devices, … hasn’t turned up anything.
Failing that, are there any that have R-R outputs, again for +/-15V supplies?
I can probably work around this, but it would be nice (simpler) not to have
to. Bandwidth is not a problem; bias current should be below 1nA.
(This involves a servo pot in an existing system that I have to treat
gingerly). It would be preferable if it weren’t too expensive (say, less than
a few bucks for a single channel).
Thanks for any suggestions!

I am in the UK. I want to know how to reduce hum & buzz when
connecting two items together.
——–
I have two pieces of electronic equipment (a PC and a tape
recorder) that I want to connect so that a signal from the tape
recorder is fed into the PC.
However if the two earths are connected then I get a buzz and hum.
This does not seem to be induced on the screened cable because if
I take the line output rather than the earphone output using the
same length of wire for each then the line out is clean (but too
weak to use).
The PC has an earth in its mains lead. The tape recorder has only
two mains wires in its mains lead with no earth.
———-
I am told there are adaptors I can use in series with the signal
lead which will stop the buzz & hum. I believe such an adaptor
isolates the two earths from one another.
An example of such a product is the Retell (model 142) Connector.
http://www.telephonerecorder.co.uk/recording/accessories/142.htm
How does such a connector or adaptor work ???
Surely it’s not simply a matter of cutting the earth lead such
that it is no longer continuous between the tape and the PC ???
Does anybody knows what is the best way to connect
DAI (PCM digital audio interface) which must be master and to connect it to
USB ?
Is there any USB chip that have slave DAI on it ?
thanks

I don’t hold a hope you’ll be able to help me but here I go, I have a
small SMD device to identify, I am completely sure it’s a transistor,
just not what type or values. It’s part of a block of 3 transistors near
a comparator used in the power controlling board of a PSU, it’s 3
terminaled, the type with a small black body and three leads, two in a
side, one lead in the opposite side (centered). The only markings I can
read in the burned shelling of the device is "1F".
hehehe very hard one. any luck? btw the device is phisically damaged, so
I doubt DMMing would help.
