TYPICAL APPLICATION
DESCRIPTION
10MHz, 6V/µs, Dual/Quad
Rail-to-Rail Input and Output
Precision C-Load Op Amps
The LT
®
1498/LT1499 are dual/quad, rail-to-rail input and
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.
