Can anyone send me the pin diagramme of the CA 3035 . Many thanks . Cornelius

Hi

I found an unknown schematic design with a CA3035 OPAMP. Maybe it helps. Check it out.

Re: CA3035

Chris . Thank you for your responce . However I am looking for a data sheet of the CA 3935 .Since this IC cannot be found anymore I want to substitute with three op-amp in its place . When successful I will post my experience . Cornelius

I think you want this.

Re: CA3035

Here are the 3 data sheet pages I have, click on each one for a larger image. Someone sent them to me a long time ago, so this is the best I have.



Also, here is an equivalent circuit I worked up long ago:

Hi Corny, (>:O/]

*CA3035 OR CA3935*??

I HAVE did offer to change the CA on two opams
(or at the best of a way, on heterodyne cheapest China receiver).
I have a magazine shematic of simple 1-V-1 receiver, similar to that I means of.
Are you need?.. I can scan it but only tomorrow.
There is also the layout.

KT315 . Thanks for your offer . I am looking forward to receive your material when you have the time to send it to me. Cornelius

Re: CA3035

Yes Bodzio , but the ECG 785 is just as absolete as the CA 3035 . That does not get us any further . Thanks anyway for your input . Regards Cornelius

Thanks Carl . This will help me on my way . Regards Cornelius

Carnelius:
Done. The IC would be change on an equivalent - I believe that is LM301.

Do you think we can use a simple radio receiver?

Thaks KT315 for your help. Because you mentioned the china receiver, do you think that in the schematic of the two box we could use in place of the receiver a normal radio receiver adjusted to 100 KHz (or what the transmitter sends)? It would be very interesting.

Re: Do you think we can use a simple radio receiver?

Miessner metal detector 1965 year (I don't remember exactly) contain a transmiter via buzzer (can be electromechanical vibrator) and an AM radio as receiver. The zero is achieved with a small movable copper plate near the ferrite. The receiver box is shielded with aquadag paint (500-1,000 ohm).
Ask on this forum who can scan for you this issue...

help me for true pin ca3035

Can anyone help me how use pin ca3035

Is there correct pin ca3035 as I painted.

[Gwil]

Your diagram is correct. See page 10 of NS document MS101115:

Note that the drawings are "third angle projection", with the pins viewed from the underside.
