Hello,

There is an evaluation board available for this device online, within the product folder, you can look at the users guide for the EVMPDK. Within this document, you can find the schematic for the hardware, if you do not want to purchase the EVMPDK, you can base your analog input design on the schemtic available to have comprable results.

The datasheet for the device will also porve helpful to evaluate the device.

Do you have a device in hand where you are expiriencing odd behavior?

Regards, Cynthia

Hi Cynthia

As I know Agilent have B2961A could test for ADC's performance
If I don't have this kind of test equipment ,how could I test ADC? use DAC or something else ?
If have training video or document ,it will be better

Thanks

Hello,

If I am understanding correctly, I belive the Precision Signal Injector EVM will be of help. This hardware provides a very clean sine wave signal at 2kHz that you can use as the input signal to the ADC. This EVM can help prove the ADC performance.

There are many training documentation available, all depends on what you are trying to do. Is there anything in specific you are trying to evaluate?

The TI Learning Center on Data converters can help navigate through the documentation to find what is most relevant to what you are looking for. I believe the app note: ADC Performance Parameters, will prove helpful, as well as TI Precision Labs- ADC
