Overview
The MC3403N is a quad operational amplifier produced by Texas Instruments. It is designed to offer low power consumption and high performance, making it suitable for a variety of applications. The MC3403N is similar in performance to the popular µA741 but with several distinct advantages, particularly in single supply operations. It can operate from a single supply voltage ranging from 3V to 36V or from dual supplies ranging from ±1.5V to ±18V. This versatility, combined with its low quiescent current and true differential input stage, makes it an efficient choice for many electronic circuits.
