LT1213/LT1214 data sheets.
The LT®1215 is a dual, single supply precision op amp with
a 23MHz gain-bandwidth product and a 50V/µs slew rate.
The LT1216 is a quad version of the same amplifier. The
DC precision of the LT1215/LT1216 eliminates trims in
most systems while providing high frequency performance not usually found in single supply amplifiers.
The LT1215/LT1216 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.
