LTC6078/LTC6079 Micropower Precision, Dual/Quad CMOS Rail-to-Rail Input/Output Ampli ers DESCRIPTIO FEATURES Maximum Offset Voltage of 25V (25C) The LTC 6078/LTC6079 are dual/quad, low offset, low Maximum Offset Drift of 0.7V/C noise operational ampli ers with low power consumption Maximum Input Bias: and rail-to-rail input/output swing. 1pA (25C) Input offset voltage is trimmed to less than 25V and the 50pA (85C) CMOS inputs draw less than 50pA of bias current. The low Micropower: 54A per Amp offset drift, excellent CMRR, and high voltage gain make 95dB CMRR (Min) it a good choice for precision signal conditioning. 100dB PSRR (Min) Each ampli er draws only 54A current on a 3V supply. The Input Noise Voltage Density: 16nV/Hz micropower, rail-to-rail operation of the LTC6078/LTC6079 Rail-to-Rail Inputs and Outputs is well suited for portable instruments and single supply 2.7V to 5.5V Operation Voltage applications. LTC6078 Available in 8-Lead MSOP and 10-Lead DFN Packages LTC6079 Available in 16-Lead SSOP and The LTC6078/LTC6079 are speci ed on power supply DFN Packages voltages of 3V and 5V from 40 to 125C. The dual am- pli er LTC6078 is available in 8-lead MSOP and 10-lead U DFN packages. The quad ampli er LTC6079 is available APPLICATIO S in 16-lead SSOP and DFN packages.
