µA741/µA741C/SA741CGeneral purpose operational amplifier

1994 Aug 31 853-0903 13721

DESCRIPTION

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.

FEATURES

•Internal frequency compensation

•Short circuit protection

•Excellent temperature stability

•High input voltage range
