Typical Application
Description
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.
For applications that require power-down, the LTC6255 and LTC6256 in S6 and MS10 packages offer shutdown which reduces the current consumption to 7μA maximum.
The LTC6255 family can be used as plug-in replacements for many commercially available op amps to reduce power and improve input/output range and performance.
