DESCRIPTIO
The LT
rail-to-rail input and output unity gain stable op amps that
feature 0.95nV/ Hz noise voltage. These amplifiers com-
bine very low noise with a 165MHz gain bandwidth,
50V/ s slew rate and are optimized for low voltage signal
conditioning systems. A shutdown pin reduces supply
current during standby conditions and thermal shutdown
protects the part from overload conditions.
The LT6200-5/LT6200-10 are single amplifiers optimized
for higher gain applications resulting in higher gain band-
width and slew rate. The LT6200 family maintains its
performance for supplies from 2.5V to 12.6V and are
specified at 3V, 5V and 5V.
For compact layouts the LT6200/LT6200-5/LT6200-10 are
available in the 6-lead ThinSOT
age. The dual LT6201 is available in an 8-pin SO package
with standard pinouts as well as a tiny, dual fine pitch
leadless package (DFN). These amplifiers can be used as
plug-in replacements for many high speed op amps to
improve input/output range and noise performance.
