I'm using the differential ADC driver AD8138 with a gain of 0.195 (Rf=390Ohm; Rg=2kOhm). It works obviously really fine on the PCB.
Then I read the Application Note AN-1026. In the chapter about the stability is mentioned that not all differential amplifiers can operate stable at fractional differential gains. I can't find this information in the datasheet of the AD8138.
Can the AD8138 operate stable at fractional differential gains in all circumstances?
