The LT1215 is a dual, single supply precision op amp with a 23MHz gain-bandwidth product and a 50V/µs slew rate. The DC precision of the LT1215 eliminates trims in most systems while providing high frequency performance not usually found in single supply amplifiers.

The LT1215 will operate on any supply greater than 2.5V and less than 36V total. These amplifiers are specified on single 3.3V, single 5V and ±15V supplies, and only require 5mA of quiescent supply current per amplifier. The inputs can be driven beyond the supplies without damage or phase reversal of the output. The minimum output drive is 30mA, ideal for driving low impedance loads.
