On this slide, the LTC6362 is shown implemented as a differential fourth order active filter with a corner frequency of 50kHz. It converts a single-ended 10V_P-P to a differential 8V_P-P signal, filters it, and drives it into the 2Msps 16-bit LTC2380-16 SAR ADC. Some differential amplifiers would oscillate in this configuration because at high frequencies the feedback provides a gain of 1, but the LTC6362 is stable at unity gain which allows this to work.
