I'm looking for RMS-to-DC converter for 100-500 kHz range. Currently I'm choosing between AD8436 and AD637 ones. My signal source is 0.5 mH 5 Ohm coil, in which 20 mV-rms voltage is induced and I'd like to get a corresponding DC-signal at the level of couple of volts. Which of theese two ICs is more appropriate for such task? Can AD8361 deal with this work?

 

Thanks.
