30MHz, 10V/µs, Dual/Quad

Rail-to-Rail Input and Output

Precision Op Amps

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.

TheLT1630/LT1631maintaintheirperformanceforsupplies

from 2.7V to 36V and are specified at 3V, 5V and ±15V

supplies. The inputs can be driven beyond the supplies

withoutdamageorphasereversaloftheoutput.Theoutput

delivers load currents in excess of 35mA.

The LT1630 is available in 8-pin PDIP and SO packages

withthestandarddualopamppinout.TheLT1631features

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.
