What is the closest ADC part number to tADC0820 or ADC08061?

[seadolphine2000]

Hi,..

I know that I asked this question many times but, I have to do it again.

What is the closest ADC part number to this one ADC0820 or ADC08061.?????

Here you are the datasheet to save your time.

Please tell me, How this new ADC affects the sampling rate or the maximum frequency of the scope.???

I need them for an oscilloscope on this page:

Thanks very much to all of you I will really appreciate your consideration.

See TLC0820 from Texas is direct replacement for ADC0820. So I used both...

Thanks penrico for your consideration, I'll search for this part, but, suppose I couldn't find it, What would be the effect another ADCs like 0804,0808,.. on this scope sampling rate and frequency.????

seadolphine2000, i do not know where you are currently located , but AD0820 is one of the easiest things to find. Well may be it will better to you to say what components you can buy and what supply channels are available for you to buy components and then forum can advice you , what things to do.

Also , if you are asking for possible replacement , it iwll be better to put your ADC requirements here.

All the best ..

artem,

Thanks for your concern, I'm from Egypt and I searched for this part allover the country and only found ADC0804, ADC0808.

I need this ADC to make the oscilloscope attached above with maximum frequency not less than 100KHz.

Could you help me.????

Try to get a free sample of them. I get from Maxim two of ADC0820, and from texas two of TLC0820, both free.

See their web pages: www.ti.com and www.maxim-ic.com, look for the part number and then request free samples.

penrico,..

Thanks very much for your help, I tried to get some free samples from National but, they told me that their are some tax problems with Egypt, so they'll hold on my request.

What shall I do.????
