Precision High Speed Op Amps  
FEATURES  
DESCRIPTION  
The LT®1057 is a matched JFET input dual op amp in  
the industry standard 8-pin configuration, featuring a  
combination of outstanding high speed and precision  
specifications. It replaces all the popular bipolar and JFET  
input dual op amps. In particular, the LT1057 upgrades the  
performance of systems using the LF412A and OP-215  
JFET input duals.
