Is the AD698 effectively a 12-bit device?
By this I mean can I connect it to a higher resolution ADC or are the effective number of
bits limited by the analog design of the AD698?
Is there a way to make higher resolution LVDT signal conditioners?
As per last response, The AD698 linearity spec typically at 75ppm will have an 13.7 bit accuracy, the worst would be at 500ppm which is a 11 bit accuracy.
So, instead of using AD7992 which is12 bit ADC, if i use 14-bit or 16-bit ADC, what would be possible good / bad out comes?
say, I'm connecting AD698 to AD8615 and then to AD7992 as reference circuit.
case 1) my o/p at AD815 is uni-polar 0 to 5V.
5V / 4096 for 12 bit ADC= 1.22mV/Step.
case 2) my o/p at AD815 is uni-polar 0 to 10V.
10V/4096 for 12bit ADC = 2.44mV/Step.
