ANALOG DEVICES LT1679CS#TRPBF Operational Amplifier, 4 Channels, 20 MHz, 6 V/µs, 2.7V to 36V, SOIC, 14 Pins

LT1679 is a quad low noise, rail-to-rail, precision op-amp. It offers both low noise and precision: 3.9nV/?Hz wideband 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. It 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. 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. Application includes strain gauge amplifiers, portable microphones, battery-powered Rail-to-Rail instrumentation, low noise signal processing, microvolt accuracy threshold detection, infrared detectors.
