I am looking for a mixer chip, that can mix two low frequency signals
Signal 1: (Local oscillator = 100 Hz - 100 KHz)
Signal 2: (Oscillator 2 = same range).

I need a difference signal from the mixer.

bs,

I don't know if this is what you were looking for or not. The link I have included in this post is to the Motorola MC12002.

Hi,

I don't have any part numbers in mind, but a four quadrant multiplier chip should also do the trick.
