  DESIGN IDEAS L Dual ADC Driver with Tightly Matched
  Gain and Phase Raises Quadrature
  by Kris Lokere
  Demodulation Performance
  Introduction
  High speed differential amplifiers help
  to drive high performance analog-todigital converters (ADCs) by providing
  balanced drive to the differential input
  stage, setting the common mode level,
  absorbing the sampling-energy, and
  taking gain to reduce the output swing
  requirement of preceding circuitry.
  In applications involving multiple
  ADCs, a compact, tightly matched
  dual differential amplifier such as the
  LTC6420-20 can further simplify the
  design by reducing the uncertainty of
  channel-to-channel variations.
  The LTC6420-20 features two
  1.8GHz differential amplifiers, each
  capable of driving 12-, 14-and 16bit pipeline ADCs at low noise and
  low distortion levels, even for input
  frequencies as high as 300MHz. The …
