DESCRIPTION
The LT
input and output unity-gain stable op amps that feature a
325MHz gain-bandwidth product, a 140V/μs slew rate and
a 85mA output current. They are optimized for low voltage,
high performance signal conditioning systems.
The LT1806/LT1807 have a very low distortion of – 80dBc
at 5MHz, a low input referred noise voltage of 3.5nV/√Hz
and a maximum offset voltage of 550μV that allows them to
be used in high performance data acquisition systems.
The LT1806/LT1807 have an input range that includes
both supply rails and an output that swings within 20mV
of either supply rail to maximize the signal dynamic range
in low supply applications.
The LT1806/LT1807 maintain their performance for supplies
from 2.5V to 12.6V and are specifi ed at 3V, 5V and ±5V
supplies. The inputs can be driven beyond the supplies
without damage or phase reversal of the output.
The LT1806 is available in an 8-pin SO package with the
standard op amp pinout and a 6-pin TSOT-23 package. The
LT1807 features the standard dual op amp pinout and is
available in 8-pin SO and MSOP packages.These devices
can be used as plug-in replacements for many op amps
to improve input/output range and performance.
