I want to use the ADA2200 to build a dual lock-in amplifier. In order to do so I want to use an ADC after it.
My question about the ADC is:
What are the important Parameter I have to look on when I want to use an ADC in connection with ADA2200?
Unfortunately the ADV in the datasheet didn't full fill my expectation, because it is only a 12 Bit ADC. I want to use an 32 Bit ADC to get an resolution in the range of nano Volts.
Thank you for your supply!
It looks like the ADA2200 datasheet has an error. As you point out, the AD7170 does not have a way of synchronizing its data conversions with the SYNCO pin of the ADA2200.
You could choose a SAR converter like the AD7091 which does have a ~CONVST input and use the SYNCO output of the ADA2200 as shown in the datasheet.
Sorry for the mistake in the datasheet.
