Final Electrical Specifications  
LT1677  
Low Noise, Rail-to-Rail  
Precision Op Amp  
February 2000

FEATURES  
DESCRIPTIO  
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: 20µV offset voltage and  
0.2µV/°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.  
Rail-to-Rail Input and Output  
100% Tested Low Voltage Noise:  
3.2nV/Hz Typ at 1kHz  
4.5nV/Hz Max at 1kHz  
Offset Voltage: 60µV Max  
Low VOS Drift: 0.2µV/°C Typ  
Low Input Bias Current: 20nA Max  
Wide Supply Range: 3V to ±15V  
High AVOL: 4V/µV Min, RL = 1k  
The voltage gain of the LT1677 is extremely high, especially  
with a single supply: 20 million driving a 1k load.  
High CMRR: 109dB Min  
High PSRR: 108dB Min  
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.  
Gain Bandwidth Product: 7.2MHz  
Slew Rate: 2.5V/µs  
Operating Temperature Range: 40°C to 85°C
