  Driver for 14-Bit, 4.5Msps ADC Operates Over a Wide
  Gain Range
  Design Note 526
  Guy Hoover
  Introduction
  The LTC В®2314-14 is a 14-bit, 4.5Msps, serial output
  ADC with an integrated high performance reference.
  The single-ended input of the LTC2314-14 is easy
  to drive and in many instances does not require a
  buffer. A driver, such as the LT6236 op amp, may be
  required for a signal that is small or has high output
  impedance. The LT6236 is a 215MHz gain bandwidth
  product, rail-to-rail output op amp/SAR ADC driver that
  features 1.1nV/в€љHz input-referred noise voltage density
  and draws only 3.5mA of supply current with a typical
  offset of only 100ВµV. The LT6236 is a good choice for
  these applications because of its high bandwidth, low
  noise, low supply current and low offset. ten depending on the value of R3, as shown in Table 1.
  Capacitor C1 and resistor R1 limit the input bandwidth
  to 68MHz. C1 also acts as a charge reservoir for the
  ADC sample-and-hold capacitor and helps to isolate the
  LT6236 from the transient that occurs at AIN when the
  ADC goes into sample mode. R1 is also used to help …
