LINER [Linear Technology]


The LT®1498/ LT1499IS   are dual/quad, rail-to-rail input and output precision C-Load™ op amps with a 10MHz gainbandwidth product and a 6V/μs slew rate.The LT1498/LT1499IS 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.
