Description
General part information
LT1679 Series
The LT1678/LT1679 are dual/quad rail-to-rail op amps offering both low noise and precision: 3.9nV/√Hzwideband noise, 1/f corner frequency of 4Hz and 90nV peak-to-peak 0.1Hz to 10Hz noise are combined with outstanding precision: 100µV maximum offset voltage, greater than 100dB common mode and power supply rejection and 20MHz gain bandwidth product. The LT1678/LT1679 bring precision as well as low noise to single supply applications as low as 3V. The input range exceeds the power supply by 100mV with no phase inversion while the output can swing to within 170mV of either rail.The LT1678/LT1679 are offered in the SO-8 and SO-14 packages. A full set of matching specifications are also provided, facilitating their use in matching dependent applications such as a two op amp instrumentation amplifier design. The LT1678/LT1679 are specified for supply voltages of ±15V, single 5V as well as single 3V. For a single amplifier with similiar performance, see the LT1677 data sheet.ApplicationsStrain Gauge AmplifiersPortable MicrophonesBattery-Powered Rail-to-Rail InstrumentationLow Noise Signal ProcessingMicrovolt Accuracy Threshold DetectionInfrared Detectors
