Efficient Rail-to-Rail I/O  
Op Amps  
FEATURES  
DESCRIPTION  
The LTC®6258/LTC6259/LTC6260 are single/dual/quad  
operational amplifiers with low noise, low power, low  
supply voltage, and rail-to-rail inputs and outputs. They  
are unity gain stable with or without capacitive loads. They  
feature1.3MHzgain-bandwidthproduct,0.24V/µsslewrate  
whileconsumingonly2Aofsupplycurrentperamplifier  
operating on supply voltages ranging from 1.8V to 5.25V.  
The combination of low supply current, low supply volt-  
age, high gain bandwidth product and low noise makes  
the LTC6258 family unique among rail-to-rail input/output  
op amps with similar supply current. These operational  
amplifiers are ideal for power efficient applications.
