FeaTures  
DescripTion  
The LT®1630/LT1631 are dual/quad, rail-to-rail input and  
output op amps with a 30MHz gain-bandwidth product  
and a 10V/µs slew rate.

Gain-Bandwidth Product: 30MHz

Slew Rate: 10V/µs

Low Supply Current per Amplifier: 3.5mA

Input Common Mode Range Includes Both Rails  
The LT1630/LT1631 have excellent DC precision over the  
full range of operation. Input offset voltage is typically  
less than 150µV and the minimum open-loop gain of one  
million into a 10k load virtually eliminates all gain error.  
Tomaximizecommonmoderejection, theLT1630/LT1631  
employ a patented trim technique for both input stages,  
one at the negative supply and the other at the positive  
supply, that gives a typical CMRR of 106dB over the full  
input range.

Active Filters  
The LT1630 is available in 8-pin PDIP and SO packages  
withthestandarddualopamppinout.TheLT1631features  
the standard quad op amp configuration and is available  
in a 14-pin plastic SO package. These devices can be used  
as plug-in replacements for many standard op amps to  
improve input/output range and performance.
