  DESIGN FEATURES 200ВµA, 1.2MHz Rail-to-Rail Op Amps
  Have Over-The-Top Inputs
  by Raj Ramchandani
  Introduction
  The LT1638 is Linear Technology’s
  latest general-purpose, low power,
  dual rail-to-rail operational amplifier;
  the LT1639 is a quad version. The
  circuit topology of the LT1638 is based
  on Linear Technology’s popular
  LT1490/LT1491 op amps, with substantial improvements in speed. The
  LT1638 is five times faster than the
  LT1490. The LT1638/LT1639 are
  “tough” op amps, with a variety of
  features that make them ideal for
  general-purpose applications. A
  unique input stage allows the LT1638
  to be operated with input common
  mode voltages up to 44V above the
  negative rail. The LT1638 dual and
  LT1639 quad op amps operate on all
  single and split supplies with a total
  voltage of 2.5V to 44V. These amplifiers are reverse-battery protected and …
