DESCRIPTION
The LTC
operational amplifi ers with low noise, low power, low
supply voltage, rail-to-rail input/output. They are unity
gain stable with capacitive load up to 100nF . They feature
6.5MHz gain-bandwidth product, 1.8V/μs slew rate while
consuming only 65μA of supply current per amplifi er op-
erating 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 currents. These operational amplifi ers are
ideal for low power and low noise applications.
For applications that require power-down, LTC6255 and
LTC6256 in S6 and MS10 packages offer shutdown
pins 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
or to improve input/output range and performance.
