  Low Noise, Precision Op Amp Drives High Resolution
  SARВ ADCs
  Design Note 1039
  Erjon Qirko and Kris Lokere
  Introduction
  The LT6018 is an ultralow noise (1.2nV/в€љHz at 1kHz)
  operational amplifier with ultralow distortion (–115dB
  at 1kHz). It has a gain bandwidth product of 15MHz,
  maximum offset voltage of 50ВµV and a maximum
  offset voltage drift of 0.5ВµV/В°C. This combination
  of features makes it suitable for driving a variety of
  high resolution analog-to-digital converters (ADCs).
  This Design Note presents circuits and optimization
  strategies to achieve the best signal-to-noise ratio
  (SNR) and total harmonic distortion (THD) when
  using the LT6018 to drive high speed 18-bit and 20bit successive approximation register (SAR) ADCs. LTC2378-20 stands out for its unrivaledВ 2ppm linearity
  performance. The best way to create a differential
  signal while maintaining linearity is by using the
  precision matched resistors in the LT5400 used on
  this demo board. A detailed theory of operation for
  the circuit shown in Figure 1 appears in Design Note
  1032 (where the LT1468 drives the LTC2377-20).
  To measure the circuit’s linearity, an ultrapure sine …
