Description
n
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.
