I was going to go back to revisit my model to debug some things but this chip seems to have disappeared in the past few months. Is it being phased out? It was the recommended solution for my parameters. It seems to give the best performance in terms of ENOB, SNR, offset for my application in the Wizard:
custom PD model +3.3V bias, 2pF, 10uA, 10GOhm, peak voltage 2V, bandwidth 25MHz, peaking 0.84, intended use at DC, 20MHz, two-stages.
Am I going to have to learn how to use Spice?
LTC6269 should now be back. Let me know if you run into any issues.
