Slew Rate: 140V/μs  
Wide Supply Range: 2.5V to 12.6V  
Large Output Current: 85mA  
Low Distortion, 5MHz: –80dBc  
Low Voltage Noise: 3.5nV/√Hz  
Input Common Mode Range Includes Both Rails  
Output Swings Rail-to-Rail  
The LT1806/LT1807 have a very low distortion of 80dBc  
at 5MHz, a low input referred noise voltage of 3.5nV/√Hz  
andamaximumoffsetvoltageof550μVthatallowsthemto  
be used in high performance data acquisition systems.  
Input Offset Voltage (Rail-to-Rail): 550μV Max  
Common Mode Rejection: 106dB Typ  
Power Supply Rejection: 105dB Typ  
Unity-Gain Stable  
The LT1806/LT1807 have an input range that includes  
both supply rails and an output that swings within 20mV  
of either supply rail to maximize the signal dynamic range  
in low supply applications.  
Power Down Pin (LT1806)  
Operating Temperature Range: 40°C to 85°C  
Single in SO-8 and 6-Pin Low Profile (1mm)  
ThinSOT™ Packages  
TheLT1806/LT1807maintaintheirperformanceforsupplies  
from 2.5V to 12.6V and are specified at 3V, 5V and 5V  
supplies. The inputs can be driven beyond the supplies  
without damage or phase reversal of the output.

Dual in SO-8 and 8-Pin MSOP Packages  
APPLICATIONS  
The LT1806 is available in an 8-pin SO package with the  
standardopamppinoutanda6-pinTSOT-23package.The  
LT1807 features the standard dual op amp pinout and is  
available in 8-pin SO and MSOP packages.These devices  
can be used as plug-in replacements for many op amps  
to improve input/output range and performance.
