DescripTion

The LT C®6081/L TC6082 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 1.3µV P-P 0.1Hz to 10Hz noise make it perfect for precision signal conditioning. The L TC6081/ L TC6082 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. L TC6081/L TC6082 is specified for power supply voltages of 3V and 5V from –40°C to 125°C. The dual L TC6081 is available in 8-lead MSOP and 10-lead DFN10 packages. The quad L TC6082 is available in 16-lead SSOP and DFN packages.

Exposure to any Absolute Maximum Rating condition for extended periods may affect device reliability and lifetime. Note 2: A heat sink may be required to keep the junction temperature below the absolute maximum. This depends on the power supply voltage and how many amplifiers are shorted.
