DESCRIPTIO
FEATURES
TheLT®1213isadual,singlesupplyprecisionopampwith
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.
