The LT1213 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 perfor-

mance not usually found in single supply amplifiers.

The LT1213/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 ampli-

fier. 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.
