DESCRIPTION

1.6V, 1µA Precision

Rail-to-Rail Input and

Output Op Amps

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 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 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 TSSOP and 5mm × 3mm

DFN packages. These devices are specified over the com-

mercial, industrial and automotive temperature ranges.
