It looks like possible substitute. I will check it out when it comes to me. I has some slight difference in offset voltave and bias/offset currents, but I think that they are not critical at all.
I tested the gs8552, and randomly selected a few pieces in the alternative experiment. The offset voltage dispersion is relatively large, ranging from 15uv to 6, 7uv. The bias current is relatively stable and relatively small at the level of tens of pa. There is also 600uv at the low end of the output. There is a negative power supply-0.6v should have no effect. The quality control is not very good, the experiment was abandoned at that time, and others saw that reuse may be the reason for the low cost.
There is a problem with your thinking. I answered other people’s questions, "You are Chinese, making a finished unisolder." What stimulates you? Opening your mouth is foul language! I'm from Hong Kong, China, any questions? There is an old Chinese saying, "Don't do bad things, don't be afraid of ghosts knocking on the door"! What is wrong with you?
Thanks to sparkybg for bringing such a good creative project, with low cost, we have made perfect use of JBC and a lot of iron! Thanks from the heart! Is it reasonable to see someone selling in public for their own benefit?
