Indeed, we do recommend an RC filter between the driver and ADC and we have answered your query about the RC filter in the couple of other threads:
From the AD8421 and…
I think the AD7631 does not require power sequencing. You are right as base from the Absolute maximum rating, there is no relation on VCC and DVDD/AVDD.
For your case, the AD7631 input operating voltage range cannot exceed beyond ±5.1V and your (bipolar) common-mode voltage cannot exceed ±0.1V from 0V (GND) as described on the page 3 (table 2) and shown in the example picture below.
PLease see attached list of the ADIs some of the latest differential ADCs with less tahn 2 LSB INL error. I have short listed this ADCs for DAQ systems application. I have included in the column on the file the throughput rate and full power…
I am designing an Data acquisition system.
I am using AD7631(18 Bit ADC) in the system.
This ADC's digital lines are interfaced with FPGA through Isolators(ISO7141CC).
The Mode of Operation of ADC during the read operation is "MASTER SERIAL…
Thank you for your advice.
I have donwloaded the evaluation software from AD7655 product page.
Downloaded technical note is attached. This document is preliminary technical note.
Is there any newest technical note ?
If you have it, please…
I am using ADR435 as a reference for a 18 Bit ADC(AD7631). The specification demands a detailed calculation of error introduced by the reference. I have done the error analysis in following way. Please confirm that the calculations are correct and…
