DESCRIPTION
The LT®6003/LT6004/LT6005 are single/dual/quad op
amps designed to maximize battery life and performance
for portable applications. These ampliï¬ers operate on sup-
plies as low as 1.6V and are fully speciï¬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 ampliï¬er speciï¬cations; input
offset voltage of 500µV maximum with a typical drift of
only 1µV/°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 ampliï¬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 à 2mm DFN packages. The dual LT6004 is available in
the 8-pin MSOP and 3mm à 3mm DFN packages. The quad
LT6005 is available in the 16-pin TSSOP and 5mm à 3mm
DFN packages. These devices are speciï¬ed over the com-
mercial, industrial and automotive temperature ranges.
