LT1801/LT1802
Dual/Quad 80MHz, 25V/µs
Low Power Rail-to-Rail Input and
Output Precision Op Amps
DESCRIPTION
The LT
®
1801/LT1802 are dual/quad, low power, high speed
rail-to-rail input and output operational amplifiers with
excellent DC performance. The LT1801/LT1802 feature
reduced supply current, lower input offset voltage, lower
input bias current and higher DC gain than other devices
with comparable bandwidth.
Typically, the LT1801/LT1802 have an input offset voltage
of less than 100μV, an input bias current of less than 50nA
and an open-loop gain of 85 thousand.
The LT1801/LT1802 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 LT1801/LT1802 maintain their performance for sup-
plies from 2.3V to 12.6V and are specified at 3V, 5V and
±5V supplies. The inputs can be driven beyond the supplies
without damage or phase reversal of the output.
The LT1801 is available in the MS8, SO-8 and the 3mm

3mm
×
0.8mm dual fine pitch leadless package (DFN)
with the standard dual op amp pinout. The LT1802 features
the standard quad op amp configuration and is available
in the 14-pin plastic SO package. The LT1801/LT1802 can
be used as plug-in replacements for many op amps to
improve input/output range and performance.
For a single version of these amplifiers, see the LT1800
data sheet.
