DESCRIPTION
The LT^®6003/LT6004/LT6005 are single/dual/quad op amps
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.
The single LT6003 is available in the 5-pin TSOT-23 and tiny
2mm × 2mm DFN packages. The dual LT6004 is available in
the 8-pin MSOP and 3mm × 3mm DFN packages. The quad
LT6005 is available in the 16-pin SSOP and 5mm × 3mm
DFN packages. These devices are specified over the com-
mercial, industrial and automotive temperature ranges.
