The LT1214 is a quad version of the same amplifier. The DC precision of the LT1214 eliminates trims in most systems while providing high frequency performance not usually found in single supply amplifiers.

The LT1214 will operate on any supply greater than 2.5V and less than 36V total. These amplifiers are specified at single 3.3V, single 5V and ±15V supplies, and only require 2.7mA 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.
