General Description
LT1211 General Description
The LT®1211 is a dual, single supply precision op amp with a 14MHz gain-bandwidth product and a 7V/µs slew rate. The LT1212 is a quad version of the same amplifier. The DC precision of the LT1211/LT1212 eliminates trims in most systems while providing high frequency performance not usually found in single supply amplifiers.
The LT1211/LT1212 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 1.3mA 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 20mA, ideal for driving low impedance loads.
