LT1677IS8#TRPBF

LT®1677 is a low noise, rail-to-rail precision op-amp. It features the lowest noise performance available for a rail-to-rail operational amplifier: 3.2nV/√Hz wideband noise, 1/f corner frequency of 13Hz and 90nV peak-to-peak 0.1Hz to 10Hz noise. Low noise is combined with outstanding precision 20µV offset voltage and 0.2µV/°C drift, 130dB common mode and power supply rejection and 7.2MHz gain bandwidth product. The common mode range exceeds the power supply by 100mV. In the design, processing and testing of the device, particular attention has been paid to the optimization of the entire distribution of several key parameters. Consequently, the specification has been spectacularly improved compared to competing rail-to-rail amplifiers. Application includes low noise signal processing, microvolt accuracy threshold detection, strain gauge amplifiers, tape head preamplifiers, direct coupled audio gain stages, infrared detectors, battery-powered microphones.
