ROSELJR Posted July 9, 2021 Report Share Posted July 9, 2021 The gain bandwidth product is 8MHZ, my magnification here: 0.41. 0.41*4K=1.6K, arguably, it is completely satisfied. VR1 is used for zero adjustment, so we can leave it alone. It looks like the op amp is very hot at 40 degrees when I use it, and I don’t know why can you tell me? Thanks in advance.

HarryA Posted July 9, 2021 Report Share Posted July 9, 2021 What are you connecting it to? Perhaps the impedance is to low? Quote Link to comment Share on other sites More sharing options...
