Hi Experts,
Seeking your guidance please:
Customer realized that as part of the realization of a test means requiring the measurement of 8 voltages he had identified the ADC ADS130E08 meeting the following criteria:
resolution > or = at 12 bits, 8 differential channels, I2C or SPI communication.
Unfortunately, their electronic team has modified certain aspects which have caused the maximum voltage to go from 3.5V to 4.5V, no longer allowing the use of this component to be possible. We are therefore looking for an alternative with similar characteristics that can accept a voltage of +/-5V and I am a little lost on all possible products (no search possible from Vin or in differential mode).
We came across the ADC ADS9817 that may meet their needs, could you tell us more about this component and others that may meet the requirements?
Thank you.
Regards,
Archie A.
Hi Archie,
The ADS130E08 and ADS9817 are two very different products. To help narrow down the selection, could you please elaborate further on the system requirements?

Hi Ryan,
Apology for the late response as the customer just got back in the office. Refer to the response below:
Concerning my needs (test tool), here is a small specification for an ADC :
At the beginning of the project the voltages to be measured were at most 3.8V and I had identified the ADS130E08 ADC which met my needs. Unfortunately our electronics team decided to review some points and the maximum voltage is now 5V. I have not found another component in your ADC range that meets my needs and is easy to use. I can't set up a reverse voltage system to use an ADC with a 0-5V input, it would disturb the measurement.
During my research I came across the ADS9817 which allows you to select several input voltage ranges but it is noted as a "preview" on your site.
I have two questions:
- Would you have one (or more) reference(s) that could meet my needs?
- Is it possible to have an ADS9817 as a sample or purchase?
