LTC6078/LTC6079 Micropower Precision, Dual/Quad CMOS Rail-to-Rail Input/Output Amplifiers FEATURES ■ ■ ■ DESCRIPTIO ■ ■ ■ ■ ■ ■ ■ Maximum Offset Voltage of 25µV (25°C) Maximum Offset Drift of 0.7µV/°C Maximum Input Bias: 1pA (25°C) 50pA (≤85°C) Micropower: 54µA per Amp 95dB CMRR (Min) 100dB PSRR (Min) Input Noise Voltage Density: 16nV/√Hz Rail-to-Rail Inputs and Outputs 2.7V to 5.5V Operation Voltage LTC6078 Available in 8-Lead MSOP and 10-Lead DFN Packages; LTC6079 Available in 16-Lead SSOP and DFN Packages The LTC®6078/LTC6079 are dual/quad, low offset, low noise operational amplifiers with low power consumption and rail-to-rail input/output swing. Input offset voltage is trimmed to less than 25µV and the CMOS inputs draw less than 50pA of bias current. The low offset drift, excellent CMRR, and high voltage gain make it a good choice for precision signal conditioning. Each amplifier draws only 54µA current on a 3V supply. The micropower, rail-to-rail operation of the LTC6078/LTC6079 is well suited for portable instruments and single supply applications. The LTC6078/LTC6079 are specified on power supply voltages of 3V and 5V from –40 to 125°C. The dual amplifier LTC6078 is available in 8-lead MSOP and 10-lead DFN packages. The quad amplifier LTC6079 is available in 16-lead SSOP and DFN packages. , LT, LTC and LTM are registered trademarks of Linear Technology Corporation.
