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 perfor-
mance 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 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.
