We need this amplifier for AEGIS Ion trap control. At lest 32 channels are needed so we will use Fastino and add 4 amplifier cards on its right side connected using flat cables. additional EEMs will be used to directly control the opto-MOS relays on the amplifier outputs I plan to use slighty modified discrete amplifiers used in Stabilizer Piezo Driver design. After replacing FETs with ones that work up to 450V I should be able to work in +/-200V range

Nice. A lot of the macroscopic trap people will like that. Is there a noise/~bandwidth~ spec already?

they say "the lower the better" :D

What's the tempco likely to be? Would be good if this amp doesn't significantly degrade Fastino in this regard. Will the R10/R17 divider be the limit?

gkasprow commented 3 years ago

I used 10ppm resistors so they seems to be the limit
