DESCRIPTION

Precision Dual/Quad

CMOS Rail-to-Rail Input/

Output Amplifiers

low noise CMOS operational amplifiers with rail-to-rail

input/output swing.

The 70μV maximum offset, 1pA input bias current, 120dB

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.
