Finding the right opamp

[ants]

I'm struggling to find the right opamp. Can someone suggest one?

1) Gain bandwidth product >2MHz
2) Output current = 25mA
3) Input voltage = +/- 10V
4) Supply voltage = +20V
5) Amps = 1
6) Price = low

Numbers 1,2,3 are of most importaance.

Thanks and regards,

Ant.

Because these datas ar not a problem for 50% of the thousands of OpAmp tpyes; the answer is realy light!
What kind of package & temp range?

Hi Karesz,

The temperature range wouldn't be a problem, and the package can be whichever is cheapest

Best regards,

You can search for Micrel, Maxim, TI, NS & Toshiba...

I still haven't found one. The priority is for 50mA. And non of the search engines I use list output current, it is always other characteristics. Sigh.

Thanks for the reply.

Added after 15 minutes:

I have found some now. I was looking in the wrong place. Tis always the way

Hi,
Iout=50 mA is a problem, be care that in worst case it has it too...
I searched for OpAmps yesterday for one my projects too, and foud OP191, they can accept up to +/-10V input , by +/-5V supply and has clean output upto RtoR!
Only, they has ca 6-10mA Ioutput...
AD8021 ha +/- 50mA, but not for 10V inputs...
What is your type pls?

Hi Karesz,

I bought half a dozen opamps that look like they would work. I've spent too long looking, I thought it was just better to buy a few and not worry about it any more.

Thanks for your suggestions, they did lead me to the right place.

y welcome!
I applyd short before an Intersil EL5x51 too, good RtoROut-type, but for +/-5V only...
As I said: BE CARE pls with WORST CASE data!!
check datasheet in detail, you can not test it in extremes at home :-(, temperatures & diverse loads at varied supply voltage & input sources is the question!
I would not test it for 100% surly, better are datasheets to basic verifications...

What is your selected type yet pls?
