Linear Technology
DESCRIPTION
The LT®1213 is a dual, single supply precision op amp with a 28MHz gain-bandwidth product and a 12V/µs slew rate. The LT1214 is a quad version of the same amplifier. The DC precision of the LT1213/LT1214 eliminates trims in most systems while providing high frequency performance not usually found in single supply amplifiers.
