LT1124/LT1125  
Dual/Quad Low Noise,  
High Speed Precision Op Amps  
FEATURES  
DESCRIPTION  
The LT®1124 dual and LT1125 quad are high performance  
op amps that offer higher gain, slew rate and bandwidth  
than the industry standard OP-27 and competing OP-270/  
OP-470 op amps. In addition, the LT1124/LT1125 have

than the OP-270/OP-470.  
Prime Grade: 70μV Max  
Low Grade: 100μV Max  
In the design, processing and testing of the device, par-  
ticular attention has been paid to the optimization of the  
entire distribution of several key parameters. Slew rate,  
gain bandwidth and 1kHz noise are 100% tested for each  
individual amplifier. Consequently, the specifications  
of even the lowest cost grades (the LT1124C and the  
LT1125C) have been spectacularly improved compared  
to equivalent grades of competing amplifiers.

Available in 8-Pin SO Packages  
APPLICATIONS  
Power consumption of the LT1124 is one-half of two  
OP-27s. Low power and high performance in both rotated  
and standard 8-pin SO packages make the LT1124 a first  
choice for surface mounted systems and where board  
space is restricted.
