Description

Gain Bandwidth Product: 30MHz  
TheLTC®6261/LTC6262/LTC6263aresingle/dual/quadop-  
erational amplifiers with low noise, low power, low supply  
voltage, and rail-to-rail inputs and outputs. They are unity  
gain stable with capacitive loads up to 1nF. They feature  
30MHz gain-bandwidth product, 7V/µs slew rate while  
consuming only 240µA of supply current per amplifier  
operating on supply voltages ranging from 1.8V to 5.25V.  
Thecombinationoflowsupplycurrent,lowsupplyvoltage,  
high gain bandwidth product and low noise makes the  
LTC6261 family unique among rail-to-rail input/output op  
ampswithsimilarsupplycurrent.Theseoperationalampli-  
fiers are ideal for low power and low noise applications.
