LTC1966 RMS-DC Converter issue

[denujith]

[FONT=&quot]Hi,[/FONT]
[FONT=&quot]I have an AC source where I want to connect it to LTC1966 to measure RMS voltage.[/FONT]

[FONT=&quot]1. I am not getting the expected output. Can I use a battery (5V) as the supply voltage and connect my AC source to IN1 and IN2 of LTC1966 (no common ground)?[/FONT]
[FONT=&quot]IF NOT,[/FONT]
[FONT=&quot]2. I have a 6-0-6 transformer which I can use for this. But I do not understand how to use the same transformer for both supply and AC input.[/FONT]

[FONT=&quot]Can anyone be a help for me, please?[/FONT]

[FONT=&quot]FYI:[/FONT]
[FONT=&quot]I am using [/FONT]this[FONT=&quot] breakout board.[/FONT]

[FONT=&quot]Regards,[/FONT]

Hi,

At first you need
* the schematic
* to read the datasheet
* to give complete information about your input signal (waveform, frequency...)
* to decide what output you expect
