The LT
1211 is a dual, single supply precision op amp with
a 14MHz gain-bandwidth product and a 7V/
s 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.
