LT1498

The LT^®1498/LT1499 are dual/quad, rail-to-rail input andoutput precision C-LoadTMop amps with a 10MHz gain-bandwidth product and a 6V/µs slew rate.

The LT1498/LT1499 are designed to maximize inputdynamic range by delivering precision performance overthe full supply voltage. Using a patented technique, bothinput stages of the LT1498/LT1499 are trimmed, one at thenegative supply and the other at the positive supply. Theresulting guaranteed common mode rejection is muchbetter than other rail-to-rail input op amps. When used as aunity-gain buffer in front of single supply 12-bit A-to-Dconverters, the LT1498/LT1499 are guaranteed to add lessthan 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 36Vand are specified for 3V, 5V and ±15V supplies. The inputscan be driven beyond the supplies without damage orphase reversal of the output. These op amps remain stablewhile driving capacitive loads up to 10,000pF.

The LT1498 is available with the standard dual op ampconfiguration in 8-pin PDIP and SO packaging. The LT1499features the standard quad op amp configuration and isavailable in a 14-pin plastic SO package. These devices canbe used as plug-in replacements for many standard opamps to improve input/output range and precision.
