The ADA4937-1/ADA4937-2 are low noise, ultralow distortion, high speed differential amplifiers. They are an ideal choice for driving high performance ADCs with resolutions up to 16 bits from dc to 100 MHz. The adjustable level of the output common mode allows the ADA4937-1/ADA4937-2 to match the input of the ADC. The internal common-mode feedback loop also p.
