The LT

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 perfor-

mance 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 ampli-

fier. 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.
