ADS8167: Reading Values From ADC

SRIDHAR P

Part Number: ADS8167

Tool/software:

Hello TI,

Currently we are working on ADS8167IRHBT. Can you please provide me the code to read the data from the all the 8 channels ?.

Is there any driver for this ADC??

Hi Sridhar,

Thanks for your question. We do not have driver code for this part. However, here is example code for a different 8 channel device that also uses SPI interface. While the parts are not the same, the code may serve as a reference.

Referring to the ADS8167 datasheet, we have a few example driver circuits. We recommend the OPA320. This is a screenshot from the datasheet of the lowest distortion and noise performance signal chain:

Hi Samiha,

If that's the case ,after modifying the code how to define in the device tree and where to place the code to load driver properly?

Hi Pawan,

This is not a driver but rather example code that may be used with the MCU, etc that you are using to interface with the device through SPI.

Okay .. understood. But we need to use a cross compiled C code to use from AM6254 processor Linux userspace to read ADC registers , for that do we have any reference . Spidev_test is minimal

How to read ADC registers similar to Spidev_test from am62x userspace is unknown for now

Hi Pawan,

I do not believe we have such a reference available.

To add, while we don’t have any such example code, there may be some open source TI ADC code for Linux on GitHub you could look through. That may be helpful.

Best regards,
