LT1498IN8#PBF

LT®1498 is a dual rail-to-rail input and output precision C-Load™ op-amp. This is 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 is 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 12bit A-to-D converters, the LT1498 is guaranteed to add less than 1LSB of error even in single 3V supply systems. The inputs can be driven beyond the supplies without damage or phase reversal of the output. This op-amp remain stable while driving capacitive loads up to 10,000pF. Applications include driving A-to-D converters, active filters, Rail-to-Rail buffer amplifiers, low voltage signal processing, battery-powered systems.
