The LT1499CS#PBF is a quad rail-to-rail input and output precision C-Load? Operational Amplifier with a 10MHz gain bandwidth product and a 6V/μs slew rate. The LT1499 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 LT1499 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 an unity-gain buffer in front of single supply 12-bit A-to-D converters, the LT1499 are guaranteed to add less than 1LSB of error even in single 3V supply systems. With 110dB of supply rejection, the LT1499 maintain their performance over a supply range of 2.2 to 36V and are specified for 3, 5 and ±15V supplies.
