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

The next best…

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…

AD827（陶封）的听音评价：
本运放一亮相便有一种“君临天下”的气势。它将AD827（塑封）原有的弊病一扫而光，表现之全面为众运放之冠，简直达到了无懈可击的地步。令笔者印象最深刻的是其巨大的能量感和霸气十足的低频…
