DESCRIPTIO
The LT^®1803/LT1804/LT1805 are single/dual/quad, low
power, high speed rail-to-rail input and output operational
amplifiers with excellent DC performance. The LT1803/
LT1804/LT1805 feature reduced supply current, lower
input offset voltage, lower input bias current and higher
DC gain than other devices with comparable bandwidth
and slew rate.
Typically, the LT1803/LT1804/LT1805 have an input off-
set voltage of 350µV, an input bias current of 125nA and
an open-loop gain of 60V/mV.
The LT1803/LT1804/LT1805 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 LT1803/LT1804/LT1805 are specified at 3V, 5V and
±5V supplies and typically maintain their performance for
supplies from 2.3V to 12.6V. The inputs can be driven
beyond the supplies without damage or phase reversal of
the output.
The LT1803 is available in the 8-pin SO package with the
standard op amp pinout and in the 5-pin SOT-23 package.
The LT1804 is available in 8-pin DFN and SO packages
with the standard op amp pinouts. The LT1805 features
the standard quad op amp configuration and is available in
a 14-pin plastic SO package.
