DESCRIPTION

Output Ampliﬁ ers The LTC®6081/LTC6082 are dual/quad low offset, low drift, low noise CMOS operational ampliﬁ ers 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 LTC6081/ LTC6082 features 100dB CMRR and 98dB PSRR. Each ampliﬁ er consumes only 330μA of current on a 3V supply. The 10-lead DFN has an independent shutdown function that reduces each ampliﬁ er’s supply current to 1μA. LTC6081/LTC6082 is speciﬁ ed 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.
