Product specification  
General purpose operational amplifier  
µA741/µA741C/SA741C  
DESCRIPTION  
PIN CONFIGURATION  
The µA741 is a high performance operational amplifier with high  
open-loop gain, internal compensation, high common mode range  
and exceptional temperature stability. The µA741 is  
short-circuit-protected and allows for nulling of offset voltage.
