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.
