Hello all,
I am writing to request a recommendation for our situation (which I believe is a fairly generic one): We are making measurements using a strain gage, with the parameters as follows:
Excitation voltage = 5 V; Sensitivity = 5 mV / V; Desired sample rate for measurement = 1 kHz or greater; Desired ADC resolution = 18 bits or greater
Can you propose a design that would allow us to make such a measurement with our strain gages? We would appreciate either a generic schematic (or app-note), or else a recommendation in terms of specific parts. I presume this would involve an ADC such as the ADS1252, in addition to an opamp and a high-precision voltage reference.
The reason we are searching for a TI-verified design is because we would like to expedite our prototype-and-production time for this particular measurement; We have looked through the application notes of some ADCs and haven't yet found a close enough match to our particular situation, hence I am bringing this question up here.
Thank you!
Cheers,
Gamin
