DESCRIPTION
The LT^®1632/LT1633 are dual/quad, rail-to-rail input and
output op amps with a 45MHz gain-bandwidth product and
a 45V/µs slew rate.
The LT1632/LT1633 have excellent DC precision over the
full range of operation. Input offset voltage is typically less
than 400µV and the minimum open-loop gain of 0.8
million into a 10k load virtually eliminates all gain error.
Common mode rejection is typically 83dB over the full rail-
to-rail input range when on a single 5V supply for excellent
noninverting performance.
The LT1632/LT1633 maintain their performance for sup-
plies from 2.7V to 36V and are specified at 3V, 5V and ±15V
supplies. The inputs can be driven beyond the supplies
without damage or phase reversal of the output. The
output delivers load currents in excess of 35mA.
The LT1632 is available in 8-pin PDIP and SO packages
with the standard dual op amp pinout. The LT1633 features
the standard quad op amp configuration and is available in
a 14-pin plastic SO package. These devices can be used as
plug-in replacements for many standard op amps to
improve input/output range and performance.
