AD636 rms to dc Operation

Hi,

 

I have a signal coming from a sensor which is DC and AC, I want to use AD636 as a RMS to DC converter.

I have few questions:

 

  1. Can AD636 be used for DC and AC signals together? My sensor has a 2.5V offset on which AC and DC signals vary.
  2. Does AD636 work on Single Supply for AC signals? I have an AC signal of the order +/- 10mV, can it sense that on a single supply? What is the operating range on single supply? what is the difference of operation for single and dual supply?

 

Regards,

 

Chaitanya
