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…
I already promoted AD847.
Also, is there any surfacemount opamp, that can be used as a direct replacement for AD843 and AD847?
What inputs are you working with? Could you provide scope shots at the outputs of the AD843 and AD847 when the error is happening?
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?Regards,Goz
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…
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…
