60Hz Notch Filter

View Full Size Image View Original Datasheet 60Hz Notch Filter

High input impedance amplifiers are ideal for buffering high impedance networks. Here a twin-T notch filter is shown to reject 60Hz signal content by more the 60dB. Small size, low valued capacitors can be used at such a low frequency with high valued resistors when using a CMOS op amp.
