The Principle and Application of Analog Active Filter MAX275 [Copy link]

MAX275 is a universal active filter produced by MAXIM Corporation of the United States. It contains two independent second-order active filter circuits, which can perform low-pass and band-pass filtering respectively, and can also achieve fourth-order active filtering through cascading, and the center frequency/cut-off frequency can reach 300kHz. MAX275 does not require a clock circuit, so compared with the switched capacitor filter, it has lower noise and better dynamic characteristics, and can be widely used in various precision test equipment, communication equipment, medical instruments and data acquisition systems.
