DESCRIPTIO
The LTC
noise operational amplifi ers with low power consumption
and rail-to-rail input/output swing.
Input offset voltage is trimmed to less than 25µV and the
CMOS inputs draw less than 50pA of bias current. The low
offset drift, excellent CMRR, and high voltage gain make
it a good choice for precision signal conditioning.
Each amplifi er draws only 54µA current on a 3V supply. The
micropower, rail-to-rail operation of the LTC6078/LTC6079
is well suited for portable instruments and single supply
applications.
The LTC6078/LTC6079 are specifi ed on power supply
voltages of 3V and 5V from –40 to 125°C. The dual am-
plifi er LTC6078 is available in 8-lead MSOP and 10-lead
DFN packages. The quad amplifi er LTC6079 is available
in 16-lead SSOP and DFN packages.
