Low Noise, Op Amp Family
DESCRIPTION
The LT
rail-to-rail input and output unity gain stable op amps
that feature 0.95nV/√Hz noise voltage. These amplifi ers
combine very low noise with a 165MHz gain bandwidth,
50V/μs 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 amplifi ers optimized
for higher gain applications resulting in higher gain
bandwidth and slew rate. The LT6200 family maintains
its performance for supplies from 2.5V to 12.6V and are
specifi ed at 3V, 5V and ±5V.
For compact layouts the LT6200/LT6200-5/LT6200-10 are
available in the 6-lead ThinSOT
The dual LT6201 is available in an 8-pin SO package with
standard pinouts as well as a tiny, dual fi ne pitch leadless
package (DFN). These amplifi ers can be used as plug-in
replacements for many high speed op amps to improve
input/output range and noise performance.
