1 / 16 page 1 LT1677 Low Noise, Rail-to-Rail Precision Op Amp February 2000 s Rail-to-Rail Input and Output s 100% Tested Low Voltage Noise: 3.2nV/ √Hz Typ at 1kHz 4.5nV/ √Hz Max at 1kHz s Offset Voltage: 60 µV Max s Low VOS Drift: 0.2µV/°C Typ s Low Input Bias Current: 20nA Max s Wide Supply Range: 3V to ±15V s High AVOL: 4V/µV Min, RL = 1k s High CMRR: 109dB Min s High PSRR: 108dB Min s Gain Bandwidth Product: 7.2MHz s Slew Rate: 2.5V/ µs s Operating Temperature Range: – 40 °C to 85°C The LT ®1677 features the lowest noise performance avail- able for a rail-to-rail operational amplifier: 3.2nV/ √Hz 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 µV offset voltage and 0.2 µV/°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.
