I have differential input signal with Vcm=0.9V, Vpp=1.0V i.e. actually span from 0.4V~1.4V.
I want to use LTC6404-2 with close loop gain set to 2V/V then pass the signal to AD9633 for sampling; however, this will require a span from -0.1V to 1.9V with Vcm=0.9v and Vpp=2.0V.
1. I want to know if I can make the ground of LTC6404 to be -1.0V and Vcm=0.9V with Vpp=2.0V i.e. -0.1V~1.9V differential?
2. Also, I want to know for the close loop gain of 2, whether LTC6404-1 is better or LTC6404-2?
