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.  
Slew Rate: 12V/µs Typ  
Gain-Bandwidth Product: 28MHz Typ  
Fast Settling to 0.01%  
2V Step to 200µV: 500ns Typ  
10V Step to 1mV: 1.1µs Typ  
Excellent DC Precision in All Packages  
Input Offset Voltage: 275µV Max  
Input Offset Voltage Drift: 6µV/°C Max  
Input Offset Current: 40nA Max  
Input Bias Current: 200nA Max  
Open-Loop Gain: 1200V/mV Min  
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.

Note: For applications requiring higher slew rate, see the LT1215/LT1216  
data sheet. For lower power and lower slew rate, see the LT1211/LT1212 data  
sheet.
