Short answer. No.
Long answer. Sort of.
We have a PAC module that has the right back end, we would just need to change the input components.
How many modules do you need? Is it a one off project, or is there an ongoing quantity?
The frequency is not an issue, its just the low voltage that you require..... On that note, you mention 0 to 736mV, how does your AC waveform appear at this voltage?? Sounds like it has a DC offset of around 368mV???
If this is correct, this adds another level of difficulty to the module front end..... Most AC voltages swing either side of 0v as you know.
