Micropower Precision, Dual/Quad CMOS Rail-to-Rail Input/Output Amplifi ers The LTC®6078/LTC6079 are dual/quad, low offset, low noise operational amplifi ers 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 amplifi er 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 specifi ed on power supply voltages of 3V and 5V from –40 to 125°C. The dual am- plifi er LTC6078 is available in 8-lead MSOP and 10-lead DFN packages. The quad amplifi er LTC6079 is available in 16-lead SSOP and DFN packages. ■ Photodiode Amplifi er ■ High Impedance Sensor Amplifi er ■ Microvolt Accuracy Threshold Detection ■ Instrumentation Amplifi ers ■ Battery Powered Applications ■ 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 DFN Packages Thermocouple Signal Conditioner APPLICATIO SU FEATURES DESCRIPTIO U TYPICAL APPLICATIO U , LT, LTC and LTM are registered trademarks of Linear Technology Corporation.
