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 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.
Note: For applications requiring higher slew rate, see the LT1213/LT1214 and
LT1215/LT1216 data sheets.
