DESCRIPTIO
The LT
speed rail-to-rail input and output operational amplifiers
with excellent DC performance. The LT1801/LT1802 fea-
ture 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 sup-
plies 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 im-
prove input/output range and performance.
For a single version of these amplifiers, see the LT1800
data sheet.
