The right high speed differential amplifier will add flexibility to signal chains that include a high speedanalog-to-digital converter (ADC). A differential amplifier can provide signal conditioning such as singleended to differential conversion, impedance transformation, and gain or attenuation. - AN-2177 Using the LMH6554 as a ADC Driver (Rev.
