DESCRIPTIO

The LT
1498/LT1499 are dual/quad, rail-to-rail input and
output precision C-Load
TM
op amps with a 10MHz gain-
bandwidth product and a 6V/
μ
s 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 specified 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
configuration in 8-pin PDIP and SO packaging. The LT1499
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 precision.
