description

LTC^®The 6081/LTC6082 are dual/quad low offset, low drift, low noise CMOS operational amplifiers with rail-to-rail input/output swings.

70μV maximum offset, 1pA input bias current, 120dB open-loop gain, and 1.3μV_P-PThe 0.1Hz to 10Hz noise makes it ideal for precision signal conditioning. The LTC6081/LTC6082 have 100dB CMRR and 98dB PSRR.

With a 3V supply, each amplifier consumes only 330μA. The devices in the 10-pin DFN package feature independent shutdown that reduces supply current to 1μA per amplifier.

The LTC6081/LTC6082 specifications are specified for 3V and 5V supply voltages and the -40°C to 125°C temperature range. The dual LTC6081 is available in an 8-lead MSOP and 10-lead DFN package. The LTC6082 quad device is available in 16-lead SSOP and DFN packages.
