LT1790 (followed by a voltage divider) is used to set the 1.0V trigger-level in my pulse distribution amplifier.

ADA4898-2 is a low-noise op-amp used in e.g. Hoffmann's "lono" design.
The input voltage noise density is specified as 900 pV/sqrt(Hz) which is very similar to the thermal noise voltage of a 50 Ohm resistor at room temperature.
This is the logic-buffer used for 1PPS in my pulse-distribution amplifier and the PICDIV2 board.
