    Hey everyone,

    I was wondering if anyone knew where I could buy a 50-60Hz notch filter IC. I've tried digikey and mouser and neither of them supply notch filters anymore. =\ whats up with that?

    Thanks.

    One op amp plus some capacitors and resistors gives you one - www.national.com/ms/LB/LB-5.pdf

    You can use just about any modern op amp in the circuit.
