For a probe that reads the reflections of water particles into water (water turbidity) I am using AD630 as an ADC. Any TI p/n that can replace this?
I need to capture a reflected light signal starting from zero and with a high noise, the more I disconnect the signal from the noise the more I can go down to the bottom in the measurement.The sore point is the ac / dc conversion, for the moment, I used the AD630 in the Lock-in Amp configuration to not use a uC (like MSP430) and write SW pages ...Do you have any ideas about it?
Thanks for using E2E, and you asked this very same question last week: https://e2e.ti.com/support/data_converters/precision_data_converters/f/73/p/695439/2563425 .
As answered in that inquiry, we do not have a replacement for the AD630. If, however, you would like to find an ADC that can be used in your application, please specify the datarate, number of bits, accuracy, interface, etc, and I'm sure we can recommend an ADC. Or, please search the ADC selection, find an appropriate ADC here: http://www.ti.com/data-converters/adc-circuit/overview.html .
A block diagram of your proposed system would also be helpful.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.
