  Risk Assessment Advice for High Reliability Amplifiers
  Tim Regan and James Mahoney Introduction
  In long life, high reliability systems, supplied power is
  provided only to essential circuitry. As a result many of
  the unpowered circuits may have voltages applied to inputs and outputs without proper supply biasing. As part
  of any diligent system safety risk assessment, a question
  often arises; will the unpowered components be damaged,
  degraded, or impair circuit performance under these
  abnormal operating conditions?
  The purpose of this article is to provide advice for what
  lies within the pins of several common amplifiers used in
  these applications. Most of the amplifiers of interest are the
  radiation hard amplifiers so indicated with a device prefix
  of RH. Another amplifier, the LT6016, is particularly robust
  with over, under and reversed polarity voltage conditions
  and is included for reference.
  With no power applied to the amplifier, forcing a voltage
  between two pins will cause a current to flow. The magnitude of this current differs from pin to pin and device to
  device. A curve tracer is used to show the current vs voltage
  characteristic when overdriving specific pin combinations.
  Referencing these curve trace plots will provide an indication of the magnitude of current flow for a particular …

  High Speed Low Noise Op Amp Family Challenges Power and Distortion Assumptions with Rail-to-Rail Inputs and Output &mdash LT Journal

  DESIGN FEATURES High Speed Low Noise Op Amp
  Family Challenges Power and
  Distortion Assumptions with Rail-to-Rail
  Inputs and Output by John Wright and Glen Brisbois
  Do the Math The tradeoff is all too familiar; low
  noise op amps dissipate high power.
  The 1.9nV/в€љHz LT6202, however,
  doesn’t follow this rule. It provides
  rail-to-rail input and output operation
  (meaning that maximum dynamic
  range can now be extracted on low
  supply voltages) with a supply current of only 2.5mA. The LT6200 offers
  even lower noise (0.95nV/в€љHz) and
  distortion, and it includes a shutdown feature for standby conditions.
  These unity gain stable amplifiers are
  well suited to fast low noise applications because of their respective
  100MHz and 165MHz gain bandwidth,
  low distortion, guaranteed noise specifications, and low offset voltage. The
  amplifiers operate on a total supply
  voltage of 2.5V to 12.6V, and are
  fabricated on Linear Technology’s high
  speed complimentary bipolar process.
  All are specified with 3V, 5V, and В±5V …
