DescripTion  
The LT®1366/LT1367/LT1368/LT1369 are dual and quad  
bipolaropampswhichcombinerail-to-railinputandoutput  
operation with precision specifications. These op amps  
maintain their characteristics over a supply range of 1.8V  
to36V. Operationisspecifiedfor3V, 5Vand 15Vsupplies.

400kHz Gain-Bandwidth Product  
The LT1366/LT1367 have conventional compensation  
which assures stability for capacitive loads of 1000pF or  
less.TheLT1368/LT1369havecompensationthatrequires  
a 0.1µF output capacitor, which improves the amplifier’s  
supply rejection and reduces output impedance at high  
frequencies.Theoutputcapacitor’slteringactionreduces  
high frequency noise, which is beneficial when driving  
A/D converters.

The LT1366/LT1368 are available in plastic 8-pin PDIP  
and 8-lead SO packages with the standard dual op amp  
pinout. The LT1367/LT1369 feature the standard quad  
pinout, which is available in a plastic 14-lead SO package.  
These devices can be used as plug-in replacements for  
many standard op amps to improve input/output range  
and precision.
