Description

Gain Bandwidth Product: 6.5MHz

The LTC^®6255/LTC6256/LTC6257 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 feature 6.5MHz gain-bandwidth product, 1.8V/µs

slew rate while consuming only 65µA of supply current

per amplifier operating on supply voltages ranging from

1.8V to 5.25V. The combination of low supply current,

low supply voltage, high gain bandwidth product and low

noise makes the LTC6255 family unique among rail-to-rail

input/output op amps with similar supply current. These

operational amplifiers are ideal for low power and low

noise applications.
