MAX7409EUA+ by Analog Devices / Maxim Integrated is a active filters designed for reliable performance in electronic applications. It is widely used in industrial, automotive, and power management systems.

Integrated circuits combine a large number of transistors and other elementary electronic components in miniaturized form into a single physical device, that is designed for a specific purpose or function and characterized by its performance of that function rather than by the behavior of its component pieces. Examples include microcontrollers, battery monitors and charge controllers, analog to digital converters, operational amplifiers, logic gates, voltage regulators, gate drivers, motro controllers, and others.
