Analog Devices / Maxim Integrated MAX22707 Precision Zero Crossing Detector

Analog Devices MAX22707 Precision Zero Crossing Detector provides a reliable and repeatable zero-crossing detection signal based on an AC line input. The MAX22707 uses switched-capacitor filters to ensure minimal zero-crossing delay while tracking change in the input frequency. The device provides higher precision and a more inherently stable output than discrete solutions. The Analog Devices MAX22707 features a low-power, precision analog filter based on the switched-capacitor technology designed for precision filtering of AC input noise.
