1. V_OUT is measured across a correctly terminated load, back matched to the device. The peak to peak voltage of the device
itself is 2 x V_OUT.
2. V_OUT is proportional to V_SET and V_SET may be an external low impedance, high stability supply. In this case the amplitude
temperature coefficient will not be guaranteed.
