DESCRIPTIO
The LT
features a 325MHz gain bandwidth product, a 140V/ s
slew rate and a 85mA output current to fit the need for low
voltage, high performance signal conditioning systems.
The LT1806 has a very low distortion of – 80dBc at 5MHz,
a low input referred noise voltage of 3.5nV/ Hz and a
maximum offset voltage of 550 V that allows it to be used
in high performance data acquisition systems.
The LT1806 has 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 maintains its performance for supplies from
2.5V to 12V and is specified 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. This device can be used as a plug-
in replacement for many op amps to improve input/output
range and performance.
