DESCRIPTION
The LTC®6078/LTC6079 are dual/quad, low offset, low 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 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 specified on power supply voltages of 3V
and 5V from –40 to 125°C. The dual amplifier 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.
