Pair 2 Analog to Digital Converter Chip

[blaqradio]

hey guys is there a successful method to pair ADC to work simultaneously, reason is i want calculate power in 6 different points, reason i want them to work simultaneously cause want to read Voltage and Current at the same time so i could get a correct value for Power, but these are read at different times they will give me incorrect answers

You can do it with a single ADC !

What you need are two " SaH(Sample and Hold) circuits" .
You trigger them both at the same time and the points you sampled are frozen for you to measure with that single ADC.

It depends on the type of ADC you use. Some ADCs come with built-in sync pins to synchronize operation of multiple ADCs. Others have more than one built-in ADC running synchronously. Others are desigend specifically for this kind of energy monitoring purpose.
The cue words to look for are "simultaneous sampling ADC"
