LT1630/LT1631
30MHz, 10V/µs, Dual/Quad
Rail-to-Rail Input and Output
Precision Op Amps
DescripTion
The LT
®
1630/LT1631 are dual/quad, rail-to-rail input and
output op amps with a 30MHz gain-bandwidth product
and a 10V/µs slew rate.
The LT1630/LT1631 have excellent DC precision over the
full range of operation. Input offset voltage is typically
less than 150µV and the minimum open-loop gain of one
million into a 10k load virtually eliminates all gain error.
To maximize common mode rejection, the LT1630/LT1631
employ a patented trim technique for both input stages,
one at the negative supply and the other at the positive
supply, that gives a typical CMRR of 106dB over the full
input range.
The LT1630/LT1631 maintain their performance for supplies
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 LT1630 is available in 8-pin PDIP and SO packages
with the standard dual op amp pinout. The LT1631 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.
