Hi,

Unfortunately 3 channel is the highest channel count available for our isolated ADC family of devices.

Can you please share some background on the application?

Hi Alexander,

thanks for the update,

I was plaing to use this IC to measure the 3Phase AC and DC voltages using tthe single IC

Hi,

Do you have a diagram showing how you would like to measure this? My concern is that the AC and DC voltages may not be referred to the same potential. This could create a risk of damage to the device.

HI,

can go through this schematic diagram, how i planed to measured is shown in that, and
is it okay to do this way or can you suggest any alternative ?

Hi Manikanta,

This should be fine for the device, though there may be issues in your system if the DC bus and AC Line aren't fully isolated.

Thanks.
