LTC6081/LTC6082
Precision Dual/Quad
CMOS Rail-to-Rail Input/
Output Amplifiers
DESCRIPTION
The LTC®6081/LTC6082 are dual/quad low offset, low drift,
low noise CMOS operational amplifiers with rail-to-rail
input/output swing.
The 70μV maximum offset, 1pA input bias current, 120dB
open loop gain and 1.3μVP-P 0.1Hz to 10Hz noise make
it perfect for precision signal conditioning. The LTC6081/
LTC6082 features 100dB CMRR and 98dB PSRR.
Each amplifier consumes only 330μA of current on a 3V
supply. The 10-lead DFN has an independent shutdown
function that reduces each amplifier’s supply current to
1μA.
LTC6081/LTC6082 is specified for power supply voltages
of 3V and 5V from –40°C to 125°C. The dual LTC6081 is
available in 8-lead MSOP and 10-lead DFN10 packages.
The quad LTC6082 is available in 16-lead SSOP and DFN
packages.
