  Application Note 87
  November 2000 Linear Technology Magazine Circuit Collection, Volume V
  Data Conversion, Interface and Signal Conditioning Products
  Richard Markell, Editor
  INTRODUCTION
  Application Note 87 is the fifth in a series that excerpts
  useful circuits from Linear Technology magazine to preserve them for posterity. This application note highlights
  data conversion, interface and signal conditioning circuits
  from issue VI:1 (February 1996) through issue VIII:4
  (November 1998). Like its predecessor, AN67, this Application Note includes circuits for high speed video, interface and hot swap circuits, active RC and switched capacitor filter circuitry and a variety of data conversion and instrumentation circuits. There are also several circuits
  that cannot be so neatly categorized. So, without further
  ado, I’ll let the authors describe their circuits.
  Note: Article Titles appear in this application note exactly
  as they originally appeared in Linear Technology magazine. This may result in some inconsistency in the usage
  of terminology. TABLE OF CONTENTS

  New 14-Bit, 800ksps ADC Upgrades 12-Bit Systems
  with 81.5dB SINAD, 95dB SFDR – Design Note 159
  Dave Thomas and Kevin R. Hoskins
  Higher Dynamic Range ADCs
  The new 14-bit, 800ksps LTC В®1419 enhances new communications, spectral analysis, instrumentation and
  data acquisition applications by providing an upgrade
  path to users of 12-bit converters. It provides outstanding 81.5dB SINAD (signal-to-noise and distortion
  ratio) and 95dB SFDR (spurious-free dynamic range)
  for frequency-domain applications, and excellent DNL
  with no missing codes performance for time-domain
  applications.
