There is a note in LTC6419 datasheet, mentioing back-to-back diodes between two input pins, limiting differnetial input voltage to 1.4V. If using a single ended signal and converting it to differtial using the LTC6419, does it mean that the input cannot exceed 1.4V wrt Gnd. If yes, this limits the input voltage to a very small value for a unity gain implementation. Is this understanding correct?
