The LT
®
6000/LT6001/LT6002 are single, dual and quad
precision rail-to-rail input and output operational amplifi-
ers. Designed to maximize battery life in always-on appli-
cations, the devices will operate on supplies down to 1.8V
while drawing only 13µA quiescient current. The low
supply current and low voltage operation is combined with
precision specifications; input offset is guaranteed less
than 600µV. The performance on 1.8V supplies is fully
specified and guaranteed over temperature. A shutdown
feature available in the LT6000 and the 10-lead dual
LT6001 version can be used to extend battery life by
allowing the amplifiers to be switched off during periods
of inactivity.
The LT6000 is available in a tiny, dual fine pitch leadless
DFN package. The LT6001 is available in the 8-pin MSOP
package; a 10-lead version with the shutdown feature is
available in DFN package. 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.
