165MHz, Rail-to-Rail Input
and Output, 0.95nV/
√Hz
Low Noise, Op Amp Family
The LT
®
6200/LT6201 are single and dual ultralow noise,
rail-to-rail input and output unity gain stable op amps
that feature 0.95nV/√Hz noise voltage. These amplifiers
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 amplifiers optimized
The LT6200-5/LT6200-10 are single amplifiers 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
specified at 3V, 5V and ±5V.
For compact layouts the LT6200/LT6200-5/LT6200-10 are
For compact layouts the LT6200/LT6200-5/LT6200-10 are
available in the 6-lead ThinSOT
TM
and the 8-pin SO package.
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.
