Line drivers VN (nV/√hz) 10 The ADA4930-1/ADA4930-2 are very low noise, low distortion,
high speed differential amplifiers. They are an ideal choice for
driving 1.8 V high performance ADCs with resolutions up to
14 bits from dc to 70 MHz. The adjustable output common
mode allows the ADA4930-1/ADA4930-2 to match the input of
the ADC. The internal common-mode feedback loop provides
exceptional output balance, suppression of even-order harmonic
distortion products, and dc level translation.
