Rail-to-Rail Input and
Output Op Amps
FEATURES
DESCRIPTION
TheLT®6003/LT6004/LT6005aresingle/dual/quadopamps
designed to maximize battery life and performance for
portable applications. These amplifiers operate on sup-
plies as low as 1.6V and are fully specified and guaranteed
over temperature on 1.8V, 5V and 8V supplies while only
drawing 1µA maximum quiescent current.

The ultralow supply current and low operating voltage are
combined with excellent amplifier specifications; input
offset voltage of 500µV maximum with a typical drift of
only 2µV/°C, input bias current of 90pA maximum, open
loop gain of 100,000 and the ability to drive 500pF capaci-
tive loads, making the LT6003/LT6004/LT6005 amplifiers
ideal when excellent performance is required in battery
powered applications.
