LT1498CN8#PBF Datasheet PDF - Linear Technology

The LT1498CN8#PBF is a dual rail-to-rail input and output precision C-Load™ Operational Amplifier with a 10MHz gain bandwidth product and a 6V/µs slew rate. The LT1498 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 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 an unity-gain buffer in front of single supply 12-bit A-to-D converters, the LT1498 is guaranteed to add less than 1LSB of error even in single 3V supply systems. With 110dB of supply rejection, the LT1498 maintain their performance over a supply range of 2.2 to 36V and are specified for 3, 5 and ±15V supplies. The inputs can be driven beyond the supplies without damage or phase reversal of the output.
