  Micropower Op Amps Work Down to 1.8V Total Supply,
  Guaranteed over Temperature – Design Note 414
  Glen Brisebois NiMH and Alkaline
  A NiMH battery has a nominal cell voltage of 1.2V, but
  it depletes to 0.9V, below which the voltage rapidly falls
  off. The LT6000 family of op amps works directly from
  two series NiMH cells taking full advantage of their entire
  charge discharge cycle. Likewise, an alkaline battery has
  a nominal cell voltage of 1.5V, but can deliver energy
  down to depletion levels of a few hundred millivolts. So,
  the LT6000 can happily operate from two series alkaline
  cells, and just as well operate directly from a 9V alkaline
  battery (6 series cells) from full charge all the way down to
  very extreme depletions (300mV average cell voltage for
  1.8V total). Sure, other low voltage op amps can operate
  at the depleted end of this battery range, but few of those
  can also tolerate a 9V supply.
  Supply Friendliness
  Some micropower op amps have annoying properties
  such as drawing excessive current at start-up (commonly
  called carrots) or when the output hits a supply rail. These
  current spikes defeat the purpose of the micropower operation by hastening battery discharge. Worse yet, they may
  altogether prevent the supply from coming up in the case …
