Precision C-Load Op Amps

DESCRIPTION

The LT

output precision C-Load™ op amps with a 10MHz gain-

bandwidth product and a 6V/μs slew rate.

The LT1498/LT1499 are designed to maximize input

dynamic range by delivering precision performance over

the full supply voltage. Using a patented technique, both

input stages of the LT1498/LT1499 are trimmed, one at

the negative supply and the other at the positive supply.

The resulting guaranteed common mode rejection is much

better than other rail-to-rail input op amps. When used as

a unity-gain buffer in front of single supply 12-bit A-to-D

converters, the LT1498/LT1499 are guaranteed to add less

than 1LSB of error even in single 3V supply systems.

With 110dB of supply rejection, the LT1498/LT1499 main-

tain their performance over a supply range of 2.2V to 36V

and are speciﬁ ed for 3V, 5V and ±15V supplies. The inputs

can be driven beyond the supplies without damage or phase

reversal of the output. These op amps remain stable while

driving capacitive loads up to 10,000pF .

The LT1498 is available with the standard dual op amp

conﬁ guration in 8-pin PDIP and SO packaging. The LT1499

features the standard quad op amp conﬁ guration 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 precision.
