Also, is there any surfacemount opamp, that can be used as a direct replacement for AD843 and AD847?
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…
Hi Phil
Thank you.
I already promoted AD847.
Best regards

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,
Kris
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?Regards,Goz
我关注的是通信领域，目前正使用DA（AD9708）和运算放大器AD811/AD847等
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…

本教程旨在考察标定运算放大器的增益和带宽的常用方法。需要指出的是，本讨论适用于电压反馈(VFB)型运算放大器——电流反馈(CFB)型运算放大器将在以后的教程(MT-034)中 讨论。
电压反馈型运算放大器的增益和带宽
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…
