TYPICAL APPLICATION

DESCRIPTION

1.3MHz, 20µA Power

Efficient Rail-to-Rail I/O

Op Amps

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

whileconsumingonly20µAofsupplycurrentperamplifier

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.

For applications that require power-down, the LTC6258

in 2mm × 2mm DFN and LTC6259 MS10 packages

respectively offer shutdown which reduces the current

consumption to 7µA maximum.

The LTC6258 family can be used as plug-in replacements

for many commercially available op amps to reduce power

and improve input/output range and performance.
