Ada4522-2 and 4522-4 are stocked at mouser. What about summing all outputs to reduce noise? Or use as buffered outputs with good reverse isolation... Daniel Em 07/04/2016 13:31, "Randy Evans" escreveu: > Has anyone looked at the ADA4522 precision op amp from Analog

2016-04-07 Thread Randy Evans
Has anyone looked at the ADA4522 precision op amp from Analog Devices. It looks very intriguing with it's extremely low offset voltage drift of 22 nV/°C maximum. The offset voltage is as high as 5 uV but this could be nulled out and it should be very stable over temperature after that. It could
