DESCRIPTIO
The LT®1677 Features the lowest noise performance available for a rail-to-rail operational amplifier: 3.2n V/√Hz wideband noise, 1/f corner frequency of 13Hz and 90n V peak-to-peak 0.1Hz to 10Hz noise. Low noise is bined with outstanding precision: 20µV offset voltage and 0.2µV/°C drift, 130d B mon mode and power supply rejection and 7.2MHz gain bandwidth product. The mon mode range exceeds the power supply by 100m V.
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 pared to peting rail-to-rail amplifiers.
