LTC6078/LTC6079

Micropower Precision,

Dual/Quad CMOS

Rail-to-Rail Input/Output Amplifiers

noise operational amplifiers 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 amplifier 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 specified on power supply

voltages of 3V and 5V from –40 to 125°C. The dual am-

plifier LTC6078 is available in 8-lead MSOP and 10-lead

DFN packages. The quad amplifier LTC6079 is available

in 16-lead SSOP and DFN packages.
