FEATURES  
DESCRIPTIO  
The LT®1678/LT1679 are dual/quad rail-to-rail op amps  
offering both low noise and precision: 3.9nV/Hz wideband  
noise, 1/f corner frequency of 4Hz and 90nV peak-to-peak  
0.1Hz to 10Hz noise are combined with outstanding  
precision: 100µV maximum offset voltage, greater than  
100dB common mode and power supply rejection and  
20MHz gain bandwidth product. The LT1678/LT1679 bring  
precisionaswellaslownoisetosinglesupplyapplicationsas  
low as 3V. The input range exceeds the power supply by  
100mV with no phase inversion while the output can swing  
to within 170mV of either rail.  
Rail-to-Rail Input and Output  
100% Tested Low Voltage Noise:  
3.9nV/Hz Typ at 1kHz  
5.5nV/Hz Max at 1kHz  
Single Supply Operation from 2.7V to 36V  
Offset Voltage: 100µV Max  
Low Input Bias Current: 20nA Max  
High AVOL: 3V/µV Min, RL = 10k  
High CMRR: 100dB Min  
High PSRR: 106dB Min  
Gain Bandwidth Product: 20MHz  
Operating Temperature Range: 40°C to 85°C  
Matching Specifications  
No Phase Inversion  
8-Lead SO and 14-Lead SO Packages  
The LT1678/LT1679 are offered in the SO-8 and SO-14  
packages. A full set of matching specifications are also  
provided, facilitating their use in matching dependent appli-  
cations such as a two op amp instrumentation amplifier  
design. The LT1678/LT1679 are specified for supply volt-  
ages of ±15V, single 5V as well as single 3V. For a single  
amplifier with similiar performance, see the LT1677 data  
sheet.
