500khz demodulator Chip

Hello everybody,

Is there a better replacement for the AD630 modulator/demodulator chip? I am trying to demodulate a 500khz modulated signal and the ad630 is to slow for it. The Opa678 looks like a suitable replacement but it is obsolete and can't find any where to buy it. Does anybody know of a better replacement that would work from 100k onwards?

Thanks!
