7 Detailed Description
7.1 Overview
The LM74 devices are general-purpose operational amplifiers which feature improved performance over industry
standards like the LM709. It is intended for a wide range of analog applications. The high gain and wide range of
operating voltage provide superior performance in integrator, summing amplifier, and general feedback
applications. The LM741 can operate with a single or dual power supply voltage. The LM741 devices are direct,
plug-in replacements for the 709C, LM201, MC1439, and 748 in most applications.
