IC demodulator

Hi, I'm looking for an IC that holds a demodulating circuit plus band-pass filters or whatever needed to accomplish the whole transformation. I'm going to use *this* IC with a sine input signal @250-750KHz (or more) and I need to extract the amplitude value. Is there on the market an IC that does what I need? It would be enough to have something which takes in the input signal, filters it, multiplies (in one or more stages) by a known frequency signal and gives out something where the 0Hz armonic can be isolated by the use of a simple low-pass filter. Low noise IC would be preferred.

Thanx in advance Stefano

Would and AM radio IC work? Something like a ZN414 perhaps (although that's not a superhet device and there are sure to be better devices around).

Here is a kit for an AM Radio based on a ZN414 copy. Works from 150KHz to

3Mhz.
