The LT

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 150

µV 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 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 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.
