Part Number: ADS9224R
One of my customers is looking for a A/D converter which can be connected to a controller with Dual/Quad SPI interface.
Can ADS9224R be used with Dual SPI mode or Qual SPI mode?
If the answer is No, could you please give me any TI ADC device which can be used with Dual/Quad SPI interface.
Your reply would be much appreciated.
Yes, the ADS9224 has a multi-SPI mode that TI calls "Enhanced SPI" (or sometimes multi-SPI on older devices that have the feature). Please read through the datasheet sections on the enhanced SPI information and let us know if you need additional information.
Some of the other higher throughput, higher resolution devices, like the ADS8900B also offer this type of interface.

In reply to Collin Wells:
Thank you very much for your reply.
This interface is the first trial for the customer to use. They need any reference design or technical document about TI enhanced SPI
to understand the SPI usage. I found the following document as one of them.
Simplify Isolation Designs Using an Enhanced-SPI ADC Interface.
Do you have any document to understand for TI enhanced SPI protocol and connection between controller and device, etc?
Thank you and best regards,
In reply to Kazuya Nakai59:
There are no documents specifically for the enhanced SPI in the ADS9224R, but we can help your customer configure the device for their application. Could you tell us some key parameters, such as desired data rate and SCLK frequency?
If they have any specific questions about the mode offerings, I can help to clarify those directly.
