, LTC and LT are registered trademarks of Linear Technology Corporation.
All other trademarks are the property of their respective owners.
The LT
6001/LT6002 are dual and quad precision rail-to-
rail input and output operational amplifiers. Designed to
maximize battery life in always-on applications, the de-
vices will operate on supplies down to 1.8V while drawing
only 13
A quiescient current. The low supply current and
low voltage operation is combined with precision specifi-
cations; input offset is guaranteed less than 500
V. The
performance on 1.8V supplies is fully specified and guar-
anteed over temperature. A shutdown feature in the 10-
lead dual version can be used to extend battery life by
allowing the amplifiers to be switched off during periods
of inactivity.
The LT6001 is available in the 8-Pin MSOP package; a
10-lead version with the shutdown feature is available in a
tiny, dual fine pitch leadless package (DFN). The quad
LT6002 is available in the 16-pin SSOP package and the
16-pin DFN package. These devices are specified over the
commercial and industrial temperature range.
