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.
