Actually, looking at the spec sheet for the ATF 34143 , I see that the
sweet spot for both NF and OIP3 seems to be around 40 mA current, so you
would want 40 mA across the 4.7 ohm resistor = 188 mV.. so I'm not
really worried about NOT getting the higher voltage but I am concerned
about the high NF...
