The LT1677IS8#PBF is a lowest noise performance Operational Amplifier for use with tape head preamplifiers. Available for a rail-to-rail operational amplifie, 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 is 20μV offset voltage and 0.2μV/°C drift, 130dB common mode, power supply rejection and 7.2MHz gain bandwidth product. The common mode range exceeds the power supply by 100mV. The voltage gain of the LT1677 is extremely high, 19 million (typical) driving a 10k load. 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 specifications have been spectacularly improved compared to competing rail-to-rail amplifiers.
