https://www.analog.com/media/en/technical-documentation/data-sheets/ADA4625-1-4625-2.pdf may also work and is half the price of the OpAmp on stabilizer. Slightly lower BW so need to re-do filter simulation.

@gkasprow do you have a spice model of the AFE of Stabilizer including all relevant noise sources?

gkasprow commented 4 years ago

All simulations are here Filters were simulated with ADISimPE. The tool has noise analysis but I'm not sure if components have right noise models because the opamp model file is encrypted.

hartytp commented 4 years ago

Thanks! I'll have a play with that.

See #4 and discussion in #2; OPA197 looks like a good candidate.

Edit: Oops, I can't close issues here.

hartytp commented 4 years ago

@gkasprow we've selected the OPA197 as our amplifier. Please close once that's on the schematic

gkasprow commented 4 years ago

I used dual version, OPA2197. The schematic is already in releases - I replaced the old one.
