RE: Seeking AD847ARZ-ND (or: chip shortages - again)

gdsalas

Hi Colin,

Can you share your application? We can search for an IC with close specs to AD847. If you can specify what specs are important for your application, it would help us pick a better suited IC alternative. Thanks!

All the best,

RE: Question about AD847JCHIPS

Gauzz

Hi Kazu,

You can find the size in mm of the AD847 chip on page 4 of the datasheet, the metalization photograph.

It is 1.70mm by 1.37mm.

May I ask why you needed the dimension?

Any Single supply highspeed opamp 5V or comparator to replace AD847AR?

kthurst

Hello,

I was using AD847 as comparator with single supply, which doesn't work well with 0V-5V (minimum specified supply range for AD847 is -4.5V to +4.5V). Obviously it was a mistake to operate it in that range. AD847 works as comparator for me but not…

Hello Rajesh,

What inputs are you working with? Could you provide scope shots at the outputs of the AD843 and AD847 when the error is happening?

Thanks,

Queries about AD8099

WayneQ

Dear Supporter,

I have a query about AD8099. I use AD8099 in my product. The package is SOIC-8.

The power supply is +/-5V. The gain is set as -10.

Input signal is square wave with the frequency of 2MHz.

After increasing the input amplitude, the output…

RE: Equivalent components for space application

Hi Sadok,

I checked the AD847-713Q status from marketing and I'm sorry to say that this part is already obsolete. While the AD847-703Q is radiation-tested, I do not think I can guarantee you the rad-hard specification that you need.

The next best…
