Ultralow Distortion Differential ADC Driver

The ADA4939 is a low noise, ultralow distortion, high speed Differential Amplifier It is an ideal choice for driving high performance ADCs with resolutions up to 16 bits from dc to 100 MHz. The output common-mode voltage is user adjustable by means of an internal common-mode feedback loop, allowing the ADA4939 output to match the input of the ADC The internal feedback loop also provides exceptional output balance as well as suppression of even-order harmonic distortion products.
