The LT
廬
1677 features the lowest noise performance avail-
able for a rail-to-rail operational amplifier: 3.2nV/鈭欻z
wideband noise, 1/f corner frequency of 13Hz and 70nV
peak-to-peak 0.1Hz to 10Hz noise. Low noise is combined
with outstanding precision: 20碌V offset voltage and
0.2碌V/擄C drift, 130dB common mode and power supply
rejection and 7.2MHz gain bandwidth product. The com-
mon mode range exceeds the power supply by 100mV.
The voltage gain of the LT1677 is extremely high, especially
with a single supply: 20 million driving a 1k 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 of even the lowest cost grade have been
spectacularly improved compared to competing rail-to-rail
amplifiers.
