  Fast and Accurate 80MHz Amplifier Draws Only 2mA
  Design Note 286
  Glen Brisebois, William Jett, Dahn Tran
  Introduction
  The 80MHz LT®1800 amplifier provides the high speed
  and DC accuracy required by low voltage signal conditioning and data acquisition systems while consuming
  a mere 2mA max supply current. The LT1800 operates
  with supplies from 2.4V to 12V and its rail-to-rail inputs
  and outputs allow the entire supply range to be used.
  DC performance is exceptional; the maximum offset
  voltage is only 350ОјV and the maximum input bias
  current is only 250nA. The amplifier is also available in
  dual and quad versions as the LT1801 and the LT1802,
  respectively. All are available in commercial and industrial temperature grades. The LT1800 is available in
  SO and SOT-23 packages, the LT1801 dual in an SO-8
  package and the LT1802 quad in an SO-14 package.
  Single Supply 1A Laser Driver
  Figure 1 shows the LT1800 used in a 1A laser driver
  application. The LT1800 is well suited to this control
  task because its 2.4V operation ensures that it is awake
  at power-up and in control before the circuit can cause
  significant current to flow in the 2.1V threshold laser.
  Raising the noninverting input of the LT1800 causes its …
