DESCRIPTION

The LT®6003/LT6004/LT6005 are single/dual/quad op amps
designed to maximize battery life and performance for
portable applications. These amplifi ers operate on sup­plies as low as 1.6V and are fully specifi ed 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 amplifi er specifi cations; 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 capaci­tive loads, making the LT6003/LT6004/LT6005 amplifi ers
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 TSSOP and 5mm × 3mm
DFN packages. These devices are specifi ed over the com­mercial, industrial and automotive temperature ranges.
